User (Legacy) Posted November 29, 2001 Report Share Posted November 29, 2001 Hi, I'm having issues with .firstlabel for axis'. When I am not zooming the chart, I set firstlabel to X - .min (where X is where I want the chart to start counting from, eg 1000 instead of 970) This works okish, but there is pretty crappy behaviour: the majority of the chart is in the negative Y axis, up to zero. I set the firstlabel correctly and everything looks great, until you set the .max to some value >= 0. Then you discover that the zero line has completely vanished, and even worse, all values ABOVE the zero line are all out of step. eg: with step of 100: -500, -400, -300, -200, -100, -nothing!-, 97, 197 Surely (especially in this case) zero should be shown and it should follow with 100, 200, etc ? ---- Also, I notice that when zooming to say 3760-whatever on the xaxis (doesn't really matter), you never get exactly that... instead you get a window starting with 3755... this occurs even when you try and use SetScrollStatus i think its called. ---- Also, I'd like to get the firstlabel thing working while zooming, so all the axis values are (say) multiples of 100. However since I can't be guaranteed that the minx I zoom to will be the first label, I can't set the .firstlabel correctly! Is this possible? Surely it should be, because otherwise the chart doesn't look so nice. Thanks, Paul Link to comment Share on other sites More sharing options...
Software FX Posted December 3, 2001 Report Share Posted December 3, 2001 1) The first problem where you get: -500, -400, -300, -200, -100, -nothing!-, 97, 197 Happens because FirstLabel is set to 97. If you have chart that breaks at zero (Min < 0, Max > 0 and BreakZero is on) you should assign FirstLabel to zero (default value). That way all calculation will go from zero up to the max and from zero down to the min. 2) I think you are talking about SetScrollView. This method will round to the step (minor step). Again FirstLabel will affect the labeling here as well. 3) This can't be done because of 2). The Zoom view is always rounded to the step. Then the step is counted from the Min + FirstLabel. -- FP Software FX, Inc. Link to comment Share on other sites More sharing options...
