We use time as our x-asix as a MM:SS.DD format. Because this format isn't directly supported I used a suggestion from these forums to come up with this format string.
chart.xAxis().setLabelFormat("{value|nn}:{={value}%60/10-0.4999999999|0}{={value}%60%10-0.004999999999|2}");
This seems to work most of the time, but occasionally I see this:
8:28.00, 8:29.00, 8:310.00, 8:31.00, 8:32.00
Note the 8:310.00 which is where 8.30.00 should be. This happens at specific numbers, such as 510 (8:30).
What seems to be happening is the second part {={value}%60%10-0.004999999999|2} is returning 10.00 when I would expect it to return 0.00.
Any suggestions on how to resolve this would be greatly appreciated.
Below is a code example that reproduces the problem. I'm running on win7 with the .NET version of the control.
ChartDirector.XYChart chart = new ChartDirector.XYChart(1135, 360);
chart.setPlotArea(45, 35, 1055, 290, -1, -1, 0x00cc00, -1, -1);
int start = 500;
double[] data = { 1,2,1,3,2,3,2,4,3,4,3,5,4,5,4,6,5,6,5,7 };
chart.xAxis().setLinearScale(start, start + data.Count());
chart.xAxis().setLabelFormat("{value|nn}:{={value}%60/10-0.4999999999|0}{={value}%60%10-0.004999999999|2} [{value}]");
List<double> xData = new List<double>();
for (int i = 0; i < data.Length; i++)
xData.Add(i + start);
chart.addLineLayer(data, 0x0000ff, "Values").setXData(xData.ToArray());
winChartViewer1.Chart = chart; |
