 ChartViewer.setMouseUsage doesn't do anything |

Hello,
I've got a ChartViewer on a JPanel. The ChartViewer is called viewer and it shows a FinanceChart with a CandleStick. When I do viewer.setMouseUsage(Chart.MouseUsageZoomIn); nothing happens. The cursor doesn't change and when I click on the chart, nothing happens. Am I forgetting something?
Regards,
Frans |

Hi Frans,
If you are using "viewer.setImage(c.makeImage());" to set the chart to the viewer, note that for Zoomable and Scrollable charts, you need to modify the code to "viewer.setChart(c);".
Hope this can help.

Hi Peter,
That did the trick, but it still not working like I want it to. Whenever I try to zoom in, the ViewPortChangedEvent is called, and it copy's the data like it's supposed to. But when I do viewer.setChart(c); to display the zoomed chart, the chart doesn't have the right height. It is displayed as a single white line (I set the backgroundcolor to white). Any idea why this is?
Regards,
Frans |

Hi Frans,
Which was your mistake, because I am having just the same problem.
