I'm a little confused about the relationship between the render and componenetDidMount methods (is methods the proper term?). Here is what I have (I excluded some code for simplicity): var Chart = React.createClass({ componentDidMount: function () { var el = this.getDOMNode(); console.log(el); d3Chart.create(el, { width: '500', height: '300' }, this.getChartState(),this.getAccessState); }, render: function () { return ( <div className="row pushdown"> <div className="d3-block"> <div

Is there a solution to configure a printing layout with @media print for the website and force highcharts to redraw/resize to container size when website is printed?

This is easy if I have explicitly set the colors of the series via a scheme or explicit RGB values, e.g. ' assuming ColorFormat.Type = msoColorTypeRGB s.DataLabels

I feel we need to extend the chartjs to support this. Can some one help me in this? 回答1: In Chart.js 2.1+ , use the borderDash option within your dataset. It takes an array of two numbers. See this codepen 回答2: Drawing a Dotted Line You don't need to extend the chart, but it would be cleaner to do it that way. Preview Script Chart.types.Line.extend({ name: "LineAlt", initialize: function () { Chart.types.Line.prototype.initialize.apply(this,

I'm using the chart control from the regular toolbox to view data from my SQL database. As you see, the bar is very wide. Is there some property or way to make it smaller, and fixed? 回答1: I did a small example binding three values and set the PixelPointWidth of dataPointCustomProperties . int[] liste = new int[] { 1, 2, 3 };//, 4, 5, 6, 7 }; chart1.Series["Series1"].Points.DataBind(liste, "sampleData", "count", "Tooltip=count"); // dataPointCustomProperties chart1.Series[

Using Python C API, I finally managed to run a script, retrieve the values from the Python variables, including NumPy arrays etc. But I failed at drawing Matplotlib charts into my Qt/C++ application. It is better to say, I have managed to save the chart's RGBA buffer to a variable using Python script, then get the value of the variable as a PyObject of buffer type, get the buffer and transform it to QImage

This is a very inefficient way to create a chart, and, as you can see in the documentation (your 2nd link reference), deprecated. Since its version 3 AmCharts supports the new chart constructor, where you can specify all properties

I do not want them overlapped! How do I go about correcting this? An image of what is happening: 回答1: You could achieve the chart as shown below with some rather careful manipulation: Basically is requires spacing out your data as shown in columns A:C but also right-aligning the horizontal axis labels, adjusting the secondary axis maximum (and format of both vertical axes, if necessary) and the Gap
