Y-Axis minimum

[XenoG]

I've just upgraded CGDevTools from 3.5 to 4.1 and I have a change in behaviour of the first tick on my y-axis. In my code I create a y-axis of type jqplrCanvasAxisLabelRenderer and I set the minimum to be zero (yAxis->Options->Min = 0;). This used (CG ver 3.5) to ensure that the y-axis started at 0, but now the y-axis starts with a negative number (.e.g. -200) and the second tick is 0. All of the points on the graph have a y-value that is 0 or greater. Any ideas how I can ensure the y-axis starts at 0.

Thanks,

Richard

Hi XenoG,
Please send me the simple testcase project.

Hi Alexander,

I've found the cause of the problem. If TIWCGJQPlot's property JQReDrawAfterResize is True, the axis minimum value is ignored. I've attached an C++ Builder project that illustrates the problem. If you prefer to recreate in Delphi, just add a TIWCGJQPlot to a form and set the default axes min to 0 and then set JQReDrawAfterResize to true. Add some data points and when you view the chart, the min value of 0 is ignored. Setting JQReDrawAfterResize to False will make the program respect the min value of 0.

Regards,

Richard

Hi XenoG,

You're right, it's a jquery plugin issue with replot function.
It's fixed on next beta build:

Code: Select all

JQPlot
- Fixed: function replot in jquery plugin. Function is called when JQReDrawAfterResize is TRUE.
- Fixed: js error in desing-time when JQReDrawAfterResize is TRUE


Thank you.

Best Regards.

Thanks Alexander. I'll grab the next beta and test that it is fixed.

Merry Christmas to you all in Portugal.
