Hi I meant, I would like to be able to use it outside of the editor - to be able to put it on a form but link it to a chart. The problem with a trackbar is it consists of a series of discrete steps, whereas a scroll bar is essentially continuous. I had not thought of looking tin the 3-d section as m...

Hi

I cannot find the zoom slider in the design time editor.

Do you mean the Chart Editor?

I looked on its zoom and scroll page and saw no zoom slider.

Is there any chance that the zoom slider could become a separate TeeChart component that we could use at run-time?

Thanks

Thanks for letting me know how it works.

i was afraid that was the way. I was hoping I would not have to do all the interpolation.

Regards

Rearranging the Series order

Hi

It would be nice if we could reorder the series by dragging their entries in the legend box into the desired order.

Stacked Line Charts

Hi 1) Is it possible to stack line charts when not all of the x coordinates are the same? 2) Actually, I would like to just display a line series which is identical to the final result of stacking several line charts (not all having the same x values), without having to actually stack the individual...

Hi Many thanks for that code. It worked great for scrolling. However, I tried to use the same code, to similarly restrict zooming. However that did not work at all. There is a difference, because zooming is usually symmetric, but when a bounding point is reached, then the zoom has to be asymmetrical...

Hi OK The problem with all the methods except using a scrollbar is that the user needs to be told somehow how to scroll the chart. A user is used to the idea of a scrollbar scrolling the screen. But a scrollbar on a TeeChart covers the whole of the side, and so you would expect the panel to scroll n...

HI I've now found out why the ChartTools were not showing at runtime. It is because I had unknowingly disabled the chart. Now, I've enabled the chart, they appear. The only problem, I now have with the 2 sets of arrows, is that only one of them gets the click event, no matter how hard I try to click...

Hi As I mentioned in my first email, that is precisely what I did. However, if say I fix the left hand horizontal minimum to be the value zero, then it is OK if I then drag the mouse leftwards, because the minimum visible chart value is then greater than zero. However, if I drag the mouse rightwards...

Hi Thanks for your reply. I was afraid that you meant standard buttons. I really want to use the Chartarrowtools as to me they are aesthetically the least worst way available for the user to scroll the axis. I have not had time to investigate why the arrows do not show up at runtime. I will try and ...

Many thanks for your reply. Sorry, but I do not understand what you mean about using little buttons. How do I put little buttons on the chart axis? My axisarrows disappear at runtime and my annotation tool fails to respond to a click event at run time although it does show up at runtime. I have not ...

Restricting scrolling/zooming

Many thanks for your helpful answers. However I probably did not explain things clearly enough when I talked about restricting scrolling and/or zooming to a region. For example if a vertical axis originally goes from 0 to 100 in values, then if a 10% zoom is made, the axis values normally then go fr...

2 sets of axisarrowtools for the same axis

Hi is it possible to have 2 sets of axis arrow tools for the same axis? I was thinking of using a pair of small arrows to scroll by a small percentage and a pair of large arrows to scroll by a much larger percentage. I was going to put the small arrow on top of the large arrow. If I click on the sma...
