charts

问题 I have a list of objects defined like this: public class ChartData { public int New { get; set; } public int Closed { get; set; } public int Canceled { get; set; } } How can I bind a winforms-chart (bar-chart type) to a List<ChartData> ? I need to have a series for each property in the object (ie, I will have 3 series) and for each point in the chart, I want to see the values for all 3 properties in the object. I managed to programatically add the series (they're visible in the chart), but

问题 I want to make a bar Chart with Winforms and F#. I have seen many other C# examples making a chart with System.Windows.Forms.DataVisualization.Charting although when i try to open that library then it says then namespace is not defined.

The code to set the number of rings: #region chartdesign Series s = chartleft.Series[0]; // a reference to the default series ChartArea ca = chartleft.ChartAreas[0]; // a reference to the default chart area Axis ax = ca.AxisX;

问题 Is there a way to move and manipulate the legend in the Pie chart for Chart.js? Specifically I want to move it to the left or right of my pie chart and have it in a list-style instead of inline. I see in the documentation that the only positions are top or bottom so I tried hiding the default legend with Chart.defaults.global.legend.display = false; And then building my own with document.getElementById('js-legend').innerHTML = myChart.generateLegend(); But this doesn't generate the colored

问题 I am working with jqplot donut and all seems to be working fine except that I am unable to give color to donut chart value % and a line that should link value % and the chart.

问题 I'm stucked in this for almost a month. I have a perfect chart in my android code using 'afreechart', however, the library does not seem to have support for exporting the chart as an image yet (since it's based on 'jfreechart' and this one does the job). I tried to get the view of the chart, convert it into canvas and save using the compress functions of the bitmap library, however everytime i try this i get a totally black image as a result. I tried this same method and it works for the

问题 I've got this Excel sheet which basically contains a lot of data. Now, this Excel sheet is updated dynamically via a macro that imports the data. So the data might change, meaning, some cells might be populated, while others won't. So I've got this formula in Sheet 2 in each cell from A2:A60 to M2:M60 which basically looks like this: =IF(Sheet1!E2<>0;Sheet1!A2;"") Meaning, if cell E2 on the row I'm in is 0, then the copied value in the new spreadsheet is nothing. Same goes for the next row:
