i am using Google visualization pie chart for showing my vote details.But the chart didn't showing the zero values and legends.
How to show all legends in Google Visualization: Pie Chart
You can simply set the sliceVisibilityThreshold option to 0. This will force all the legends to show.
var options = {
sliceVisibilityThreshold: 0
};
var data = /* ... */;
var chart = new google.visualization.PieChart(/* ... */);
chart.draw(data, options);
What I did was to add a small value (0.005) to each of the values. When setting the sliceVisibilityThreshold: 1/25000, (1/25000 = 0.004) the slice/legend will be shown but the value will still be 0% due to rounding.

Im newbie in js and anychart
I have anychart chart like this
how can i fill the color based on range like risk matrix.
*Result What i want
This is my code
// create data
var data = [
{x: 2.88, value: 3.12},
{x: 1.9, value: 2.3}
];
// create a chart
var chart = anychart.scatter();
// adjust scale min/max
chart.xScale().minimum(0).maximum(5.0);
chart.yScale().minimum(0).maximum(5.0);
// divide scale by three ticks
chart.xScale().ticks().interval(1.0);
chart.yScale().ticks().interval(1.0);
// create a bubble series and set the data
var series = chart.marker(data);
// enable major grids
chart.xGrid().enabled(true).stroke('0.1 blue');
chart.yGrid().enabled(true).stroke('0.1 blue');
var yAxis = chart.xAxis();
// set the chart title
chart.title("Quadrant-like Scatter Bubble Chart");
// set the container id
chart.container("container").draw();
});```
To get a risk matrix in the result, it’s better to use the Heatmap module.

I am using iOS Charts with Swift 3.
I have a 100 x 100 PieChartView that renders the pie chart, but it's not filling the view (an NSView, to be precise). The gray box is the view and there's a large gap between the pie and the edge.
I have confirmed that the view is 100 x 100:
print(graph.frame) //<-- (25.0, 65.0, 100.0, 100.0)
So I assume there is something I need to configure in the pie chart to allow it to be the full size in the view. Here's what I've tried so far to no avail:
graph.holeRadiusPercent = 0.7
graph.transparentCircleRadiusPercent = 0
graph.legend.enabled = false
graph.chartDescription?.enabled = false
graph.minOffset = 0
Any ideas?
Found it! It turns out my graph was rendering the values in the pre-selection state. If I clicked on a pie segment, it would grow larger.
So by setting this property, the graph fills the available space:
ds.selectionShift = 0 //'ds' is my PieChartDataSet
I hope that helps someone else.
I Used this parameter to create chart image

I am creating Stacked bar chart using google Visualization api.
I want to show the data in clear and proper spacing ,Stuck from 2 days .Thank you for help.
I created an Microsoft Chart in C# and added the following legend:
Legend legend = new Legend {
Alignment = StringAlignment.Center,
Docking = Docking.Bottom,
Enabled = true,
IsDockedInsideChartArea = false,
TableStyle = LegendTableStyle.Wide,
};
Part of the legend appears on top of the X axis ... Any idea why?
How can I solve this? Can I add a top margin to the legend?
Thank You,
Miguel
In my code I let the Chart create the legend object itself, this is the VB code, but maybe it's useful to you:
aChart.Legends.Clear()
aChart.Legends.Add("Default")
aChart.Legends(0).BorderColor = Color.Black
aChart.Legends(0).Docking = Docking.Bottom
aChart.Legends(0).IsDockedInsideChartArea = False
aChart.Legends(0).TableStyle = LegendTableStyle.Wide
aChart.Legends(0).Alignment = StringAlignment.Center
you need to create a chart area:
p_Chart.ChartAreas.Add(new ChartArea(MAIN_CHART_AREA));
then set both your series and you legend to this area:
legend.DockedToChartArea = MAIN_CHART_AREA;
series.ChartArea = MAIN_CHART_AREA;
I'm creating a JFreeChart and passing it to be displayed on a Jasper pdf report. This is my code for creating the chart
JFreeChart chart = ChartFactory.createLineChart(
null, // chart title
null, // domain axis label
scale + " Range", // range axis label
dataset, // data
PlotOrientation.VERTICAL, // orientation
false, // include legend
true, // tooltips
false // urls
);
parameters.put("chartpath", chart.createBufferedImage(1600, 800));
The chart shows up very small in the pdf report and is unreadable. I tried to increase the dimensions in the above createBufferedImage function, but it's not working. Any input will be appreciated.
This is probably to do with the size of the element in the report itself rather than the chart that's being generated and passed as a parameter.
If you are using an element in the jrxml, check the width and height properties.
If not, could you explain how you are using the "chartpath" property in the report?
