When I am loading new financialdemo there is an error (please see attached image). I was updated only tamultiseries.pas from http://svn.freepascal.org/svn/lazarus/trunk/components/tachart/. Which other files I must update? Regards, Kamen

I uploaded a small modification today which takes care of your request: the color of the body border and the tails of the CandleStick series is determined by the property CandleStickLinePen. If you set this color to clDefault these lines will be painted in the color of the body. Please see the updated "financial" demo. >> How can I add HorzScrollBar or something like this and keep the scale of CandleStick? In TAChart you can zoom by left-dragging a rectangle across the chart. And you can pan the zoomed window by dragging with the right-mouse button down. Or you can implement more sophisticated features by using the chart tools. In addition, there is a TChartNavScrollbar which you can use to scroll the zoomed window across the chart range. You just have to link its "Chart" property to the chart which you want to control. The "Min" and "Max" of the scrollbar map to the data range used in the chart. To get day-by-day scrolling set the scrollbar's Min and Max to the corresponding values of the horizontal axis (Chart1.GetFullExtent.a.x and b.x) at run-time. Moreover, there is also a TChartNavPanel which displays the full range of the data and encloses the zoomed range by a rectangle. You can drag this rectangle over the chart, and the zoom window will follow automatically. Having "MiniMap" true displays a miniature chart for rough orientation. Again, you have to couple it to the chart of interest by means of the "Chart" property. In my feeling, however, there are still some weaknesses of this component, maybe I can look after them in the next days. BTW: Do you know the TAChart documentation http://wiki.lazarus.freepascal.org/TAChart_documentation? -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
