Thank you,
My xml data like this:
<chart showValues="0" setAdaptiveYMin="1" bgAlpha="0">
<set label="ads_octopus" value="20090510" />
.....
</chart>
Could you tell me how to turn off y-axis, and replace the same with trendlines. sorry, i don't konw what's 'trendlines', you mean replace it by other y-axis?
