Hey Steve, Thank for the information... I will contact next time directly the support team. have a nice week Stan

Hi Steve, I also gave up long ago and ordered also the latest version of ChartFX. Waiting for my boss' approbation... Did you encounter any problem when updating ? I hope that the part of the forum for the latest version is a little bit more lively ^^# best, Stan

Hey Steve, I've got the same problem...and went back to VS2005 for the moment. Did you find a solution, Steve ? Best, Stan

Hello, I need help. when I am trying to set a graph with a "reverse" X-axis in log (by "reverse", I mean the maximal value at left side and minimal value to the right), the grid simply disappears ... Someone does have the solution or the idea what I may have done wrong ? Here a part of the code that I used with ChartFX 5.1: m_pChartFX->Axis->Item[AXIS_X]->LogBase = 10; m_pChartFX->Axis->Item[AXIS_X]->GridStyle = CHART_SOLID; m_pChartFX->Axis->Item[AXIS_X]->Grid = true; m_pChartFX->Axis->Item[AXIS_X]->Visible = true; m_pChartFX->Axis->Item[AXIS_X]->AutoScale = false; m_pChartFX->Axis->Item[AXIS_X]->Min = MAX_VALUE; m_pChartFX->Axis->Item[AXIS_X]->Max = MIN_VALUE; Best,

Hello, I solved my problem. I used the example delivered with the software, reacting on mouse events. i do not know if it was the best solution but it works for me if i drag not too fast the constant line. if you are interested the code is in attached file. (of course you need dll file from ChartFX to make it work.) Best Stan

Hello, For the moment, the user can click on the Chart to define a constant line. I would like to allow them to move this constant line. Just wondering if there is a simple way to allow the user to drag a constant line into the Chart with the mouse ? (the m_pChartFX->AllowDrag = TRUE; concerns only the curves and not the constant lines) Best regards, Stan
