atopf	Posted - 10 Dec 2019 : 03:32:12 Hello, is it possible to alter the position of the scrollbar in such a way, that its initial position shows the latest data points (the farthest on the right) instead of the oldest. Thx in advance! Alex

quinncurtis	Posted - 14 Jan 2020 : 11:03:23 We tested it on two of our example programs: TimeVariableControlCharts.XBarRChart and TimeVariableControlCharts.XBarRSigma and it worked as we describe. Do the same thing on your end. If it works for those examples, but not for your own program you will have to try and create some sort of simple example which reproduces what you are doing in the setup which causes the issue. Then you can send that to us as a project and we can determine the cause. You probably have more than one update taking place. You might want to comment out different events after the initial update to try and find the block of code causing the problem.
atopf	Posted - 14 Jan 2020 : 04:39:20 This doesnt seem to help. There is still an initial flickering (it first shows the oldest data points for a brief moment, before navigating to the latest data points) Any other ideas?
quinncurtis	Posted - 10 Dec 2019 : 10:17:53 Call setRescaleOnUpdatePosition with an argument of ChartObj.SCROLLBAR_POSITION_MAX at somepoint in the chart setup. The default is ChartObj.SCROLLBAR_POSITION_MIN. this.setEnableScrollBar ( true); this.setRescaleOnUpdatePosition( ChartObj.SCROLLBAR_POSITION_MAX); . . . this.setEnableCategoryValues( false); this.setEnableCalculatedValues( true);
