Re: FirstDisplayedIndex & Zooming

From the examples I worked out that I had to interpolate the YValue from the XValue at the minimum and maximum bottom axes values.

Thanks anyway, and thanks for the great examples.

FirstDisplayedIndex & Zooming

Hi,

After zooming I was expecting the First/LastDisplayedIndex of a series to have changed but it is not. I need to get the first and last visible YValues in the Charts AfterDrawEvent. How do I do this?

Thanks

Re: Panning on Mobile

The problem is not with loading the map, it is with panning or doing anything else after loading the world series.

Re: Panning on Mobile

Thanks. Additional there is a general problem on Android devices if using TWorldMap.wmWorld, even on the fastest devices. This slows down the whole app to the point that it is unusable. Zooming and panning are particularly slow. If TWorldMap.wmEurope27 is used instead, it is more acceptable, but now...

Panning on Mobile

Hi,

When panning, using your inbuilt procedures, the amount the map moves is not in relation to how much you move your finger, it is a factor of 2 to 3 more on both iOS and Android. Using a mouse it is one-to-one.

I am using a world map. Is there any way of adjusting this?

Thanks

Re: TWorldSeries Pan and Zoom on Mobile

I more or less have this working as I want, except zooming lags on Android devices. Do you have any recommendations?

Couple of questions on this.

How can zoom be prevented going too far in or out?

How can the aspect ratio be mainained when zooming?

Thanks.

Re: TWorldSeries Pan and Zoom on Mobile

I have been unable to get gestures to work correctly with maps. Do you have an example. Why can't your internal methods work. Panning works fine, and zooming works fine if only one of them is enabled but if both are enabled only the zoom works on mobile devices.
