Re: static axis grid when zooming

Thanks Narcis! That is exactly what i was looking for. only one slight issue with it: for some reason when drawing the lables manually as you suggested, the label's color seems to default always to black. though i've set previously: tChart1.Axes.Top.Labels.Font.Brush.Color = Color.White; This is imp...

Re: static axis grid when zooming

Hi Sandra, Thank you for your reply! I'll try to further explain what i'm looking for. perhaps the term "zoom" is confusing here. Basically i set the axis.Minimum & axis.Maximum to different values, which achieve a sense of "zooming" of the entire chart to the viewer. (I applied this to the mouse wh...

static axis grid when zooming

Hi, I'm using the top axes in a chart and applied zooming in and out manually using the axis Minimum & Maximum properties. This works just fine for me. The issue is that when zooming in or out the axis grid (together with ticks and labels) change position to their new position. I wish to have the ax...

Double.NaN in a series

Hi, I've added an array to a series (fastline or line) which contains several Double.NaN and set the Series DefultNullValue to Double.NaN. But I get an Overflow exception when displaying it. If I change all Double.NaN to nulls and keep the DefultNullValue as null it works ok. Am I missing something ...

Excellent. problem 1 - solved. Regarding problem 2: Using the MarksTip tool, is there a way I can get the x value between 2 of the series' points currently pointed to by the mouse, in order to use it in the interpolation of y ? Also, how can i tell which is the series currently pointed to by the mou...

View only active series in legend

Q1: I'd like to see in the legend only the currently active series, how could I accomplish that ? Q2: when hovring the mouse over a fastline series (or line series) The MarksTip tool shows the value of the last point in the series before the location of the mouse instead of the actual calculated val...

how to check if chart is scrolled and the scroll amounts

Hi, I have an x-axis which has 2 types of values (one with large values and the other with very small values), which the user can switch between them. Whenever the chart is zoomed or scaled, and the x-axis gets the other set of values, the scale changes. I want to return to the same zoom/scale appli...

e.ValueIndex not updating in GetAxisLabel

Hi, I'm using Teechart for .net v3. In the GetAxisLabel() event the e.ValueIndex is -1 for each label (while the e.LabelText does show the displayed text). is this a bug ? btw, I'm not using custom labels. How can I get the underlying value for the label in the GetAxisLabel() event ? Regards, Yair

OK, thanks.

Another question about this:
How can I get the min and max displayed values when zoomed (In order to figure out the required exponent) ?

Hi Narcis, Thanks a lot for your continuous support. Is there a way to show the exponent just on the edge of the axis, so it applies to all the axis' values, like in the Matlab's plot. Also, when zooming in/out of a chart in Matlab's plot it reconfigures the exponent according to the values displaye...

Automatically set an axis scale precision

I have an array of double values for the X of a fastline series which are very small (~10e-9), but the chart shows all of them on the X axis as 0's.

Is there a way to have the chart automatically scale the X-axis to a precision based on the values it has ?

Thanks and Best Regards,
Yair

change a series type at realtime

I have a list of series which i attach to different charts at realtime. I'd like to be able to change the type of a series after it was inserted into the chart (eg. from FastLine to Points), if possible using the same series object. (now I create a new series for each replacement and copy the attrib...
