HELP PLEASE - Fuzzy Messy Weird Area Chart redraw on slider movement

[Dominic Boston]

Hi All,

I normally don't post on forums but I'm really stuck.

Please take a look at this website and move the slider, the problem will become very apparent as you move the slider around - 

https://redvector.co.uk/gencharts/index2.php

It redraws a perfect chart, but make's a right mess in the process.

Image attached if you're too scared to click the link!

Many Thanks for your help.

when loading on v41, the graph disappear every time you touch the slider,

v42 - v46 you get the above problem.

Thanks

Open the debugger and add a breakpoint to your chart2.draw() call in reDrawChart2.  Then click on a slider.  You will see that the chart is redrawn 7 or 8 times each time you make a slider change.  Each time, it starts the startup animation, which I guess is proceeding simultaneously for all redraws.

There is also a failure the first time you try to call reDrawChart2.  So you should check whether your overall flow is correct.

Thanks Daniel,

I realise I’m calling the start up animation on every redraw. Probably unwise!

And I’ll check flow.

Thanks

Dom!
