Hi,
Im tryin to create an effect where I have a static point on the Y Axis and I want to perform zoom in, so what I did is to increase or decrease the Max visible range, what I’m left with is the rubber band effect where my static point isn’t static anymore because the point in “Stretching” in the direction I’m zooming.

Hi,

I’ve been looking through ways to have to y-Axis scale for really small changes/values.

For example, I’m attempting to plot 10 values between 0.99300 to 0.99400, and the changes between points can vary between 0.001 to 0.0001 or so (basically, really small changes)

However, my y-Axis seems to always start at 0 and the y-Axis major ticks are always at most a 0.1 difference, making the graph look flat.

I’d like to achieve the following:
– Scale to the smallest value i can scale to.
– Have my y-Axis to not necessarily start at 0.

I’ve tried the following:

Setting up y-Axis:

    self.yAxis = [SCINumericAxis new];
    [self.yAxis setStyle:axisStyle];
    self.yAxis.axisId = @"yAxis";
    [self.yAxis setGrowBy:[[SCIDoubleRange alloc]initWithMin:SCIGeneric(0) Max:SCIGeneric(0.1)]];
    [self.yAxis setAutoRange:SCIAutoRange_Always];
    [self.chartSurface attachAxis:self.yAxis IsXAxis:NO];

Regards.

I am currently evaluating and trying to find out if it is possible to draw the y-axis in the middle of the chart. Is this possible?

Like the alignment for left and right an alignment like “middle”. The sample only shows left and right alignment.
If it is not build in. Would it be possible to code a custom position? (But not by changing the source of SciChart but rather extending it).

I would need it for 2 scenarios:
A “running” chart like the FiFo Chart of the samples with the y-axis in the middle.
Like so (the pipe being the y-axis). First line the initial state. Second line after 3 ticks:
-1-2-3-4-5-|-6-7-8-9-
-4-5-6-7-8-|-9-10-11-12-

And a y-axis fixed chart like: y-axis at position 0 and the axis extending to the left with negative values and extending right with positive values (but at any possible position not just 0).

-(-5)-(-4)-(-3)-(-2)-(-1)-|-1-2-3-4-5-

I would have the same question for the x-Axis but I haven’t looked into x-axis configuration myself yet.
