This article tries to explain how we can make some interesting charts such as Pie chart, Doughnut chart, Histogram chart and Linear chart to represent data. The following picutures are examples of how they look like.Bts reaction to you having a cute laugh
My project contains two libraries in order to create one of those charts. The first library SVGObjects contains some of the common svg objects that we need to create a well formatted svg document.
Of course, we can add more if needed.Facebook email scraper
We'll use the second library Charts to format the charts. Notice that we only have one way to input data to be transformed, this is using a DataTable. Of course, we can modify the projects, adding more interfaces in order to accept other types of objects that contain data such as Hashtable s or XmlNode s.
Charts is a hierarchical class library. All classes used to create those charts have the method GenerateChart. The only thing that we have to do to call this method is to pass in the chart data with a DataTable object containing two columns, one with the chart labels as strings and one with the chart values as doubles.
It's very easy to create charts with the Chart library. We just need to instantiate an object of the required chart class e.Elasticity of demand and supply questions and answers
PieChartpassing these parameters to the constructor: width, height and number of legend items if we want it. Afterwards we have to call the method GenerateChart and save the XmlDocument that it has given us. The objects that are used by SVGObjects library contain the main attributes to make a chart. In some cases, the attribute names are not the same as the names of the svg elements they represent and some of their properties are omitted. This is to simplify the object creation.
To address that, the Charts library needs to transform those objects to a well formatted svg document. In order to do this, the library uses an XSLT template. There are some differences between those tags, let's have quick a look. Mainly, the difference reside in the browser the client is using and the HTML version in that the document is written. The iframe tag works in most browsers. This is a pitty, due to Adobe announced at the begining of that they were not going to support this pluggin any more.
I guess that Silverlight has some part of guilt.Every second Tuesday, we send a newsletter with useful techniques on front-end and UX. Pie charts, even in their simplest two-color form, have traditionally been anything but simple to create with web technologies, despite being incredibly common for information ranging from simple stats to progress indicators and timers.
This solution is the best in terms of markup: it only needs one element and the rest is done with pseudo-elements, transforms and CSS gradients. We will work on making it flexible later. We might be tempted to use skew transforms for the percentage part, but as a little experimentation shows, they prove to be a very messy solution. Now, we can proceed to styling the pseudo-element that will act as a mask:.
You can see in Figure 3 where our pseudo-element currently lies relative to the pie element. Note: Take care not to use background: inherit;instead of the background-color: inherit;otherwise the gradient will be inherited too!
Our pie chart currently looks like Figure 4. This is where the fun begins! We can start rotating the pseudo-elementby applying a rotate transform. You can see how it looks for a few other values as well, in Figure 5. You can see this in action in Figure 7. All this is good, but how do we style multiple static pie charts with different percentages, which is the most common use case?
Ideally, we want to be able to type something like this:.

First, we will explore how we can do it with inline styles, and then we could always write a short script to parse the text content and add said inline styles, for code elegance, encapsulation, maintainability, and perhaps most importantly, accessibility. The challenge to controlling the pie chart percentage with inline styles is that the CSS code that is responsible for setting the percentage is set on the pseudo-element.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. A much improved decorator system has been introduced, allowing for greater flexibility and less complexity. See releases for more information. There we will try to showcase the really cool things you can do with this library. This README will try to keep things as simple as possible so that everybody can get up and running as fast as possible.
This library uses react-native-svg to render its graphs.
Visualization: Pie Chart
Creating beautiful graphs in React Native shouldn't be hard or require a ton of knowledge. We use react-native-svg in order to render our SVG's and to provide you with great extensibility. We utilize the very popular d3 library to create our SVG paths and to calculate the coordinates. We built this library to be as extensible as possible while still providing you with the most common charts and data visualization tools out of the box. We're very proud of our "decorator" support. All charts can be extended with "decorators", a component that somehow styles or enhances your chart.How many times can you press the spacebar in a minute
Simply pass in a react-native-svg compliant component as a child to the graph and it will be called with all the necessary information to layout your decorator. See each chart for information on what data the decorator will be called with. If you want to test out the library you can clone this repository and run it.
We suggest that you test out the storybooks that we've implemented. Most of the charts are implemented with knobs so that you can tweak most properties and see their behavior live.A path element is used to create a path on the SVG. The above code defines the following path starting from the point ,0creates a line from ,0 to 75,another line from 75, toand finally a closing path to ,0.
Learn more about SVG path here. We already learned about Scales in D3. The d3. In an ordinal scale, the order is of utmost importance and not the difference. In the above example, the color variable will act as a scaling function which will return specified color for the specified index.
For example, color 0 will return 4daf4a, color 1 will return eb8 color 2 will return ff7f00 and so on. If a value at the specified index does not exists in the specified range then it will restart from 0. You can read more about ordinal scale here. It calculates the start angle and end angle for each wedge of the pie chart. These start and end angles can then be used to create actual paths for the wedges in the SVG.
In the above example, we defined a d3. This function calculated certain fields for the pie chart like startAngle and endAngle along with the data values. These are the paths that will create our pie's wedges. Arcs need an inner radius and outer radius. If the inner radius is 0, the result will be a piechart, otherwise the result will be a donut chart. We need to supply these generated arcs to our SVG path elements.
We first define all our variables like width of the svg and, height of the svg. We calculate the radius as Math. For this, we choose whichever of the width and height is the minimum value. The above code appended a group element to our SVG to group all the pie elements together. Next, we define our color scale as an ordinal scale. When we pass an index of a value in data array to the color scale, it will return the corresponding color value.Public Domain.

If you set the is3D option to trueyour pie chart will be drawn as though it has three dimensions:. A donut chart is a pie chart with a hole in the center. You can create donut charts with the pieHole option: The pieHole option should be set to a number between 0 and 1, corresponding to the ratio of radii between the hole and the chart.

Numbers between 0. Values equal to or greater than 1 will be ignored, and a value of 0 will completely shut your piehole. You can't combine the pieHole and is3D options; if you do, pieHole will be ignored. Note that Google Charts tries to place the label as close to the center of the slice as possible.
If you have a donut chart with just one slice, the center of the slice may fall into the donut hole. In that case, change the color of the label:.Ios tank simulator
PieChart document. By default, pie charts begin with the left edge of the first slice pointing straight up. You can change that with the pieStartAngle option: Here, we rotate the chart clockwise degrees with an option of pieStartAngle: So chosen because that particular angle happens to make the "Italian" label fit inside the slice.
You can separate pie slices from the rest of the chart with the offset property of the slices option:. To separate a slice, create a slices object and assign the appropriate slice number an offset between 0 and 1. Below, we assign progressively larger offsets to slices 4 Gujarati12 Marathi14 Oriyaand 15 Punjabi :.
We also used the pieStartAngle to rotate the chart degrees, pieSliceText to remove the text from the slices, and tooltip. You can set a value as the threshold for a pie slice to render individually. This value corresponds to a fraction of the chart with the whole chart being of value 1.
Any slices smaller than this threshold will be combined into a single "Other" slice, and will have the combined value of all slices below the threshold. The google. The visualization's class name is google. The background color for the main area of the chart. Can be either a simple HTML color string, for example: 'red' or ' 00cc00'or an object with the following properties.
An object with members to configure the placement and size of the chart area where the chart itself is drawn, excluding axis and legends. The colors to use for the chart elements. An array of strings, where each element is an HTML color string, for example: colors:['red',' ']. Whether the chart throws user-based events or reacts to user interaction. If false, the chart will not throw 'select' or other interaction-based events but will throw ready or error eventsand will not display hovertext or otherwise change depending on user input.
The default font size, in pixels, of all text in the chart. You can override this using properties for specific chart elements. The default font face for all text in the chart. Draws the chart inside an inline frame. Note that on IE8, this option is ignored; all IE8 charts are drawn in i-frames. An object with members to configure various aspects of the legend.
