Hi,
Please take a look at the attached screenshot first.
I have a chart configured to draw some data. I need to draw SCIAxisMarkerAnnotation on Y axis. And it seems that annotation has alignment by right side of axis area. Is there a possibility to change it to left side of axis area?

Hi, guys
it seems that i had found a mistake:
At SCICursorModifierStyle class if i try to set up axisVerticalTooltipCornerRadius property it lead to changing of axisHorizontalTooltipCornerRadius
Please take a look
Best regards,

Hi, guys
I’m working with SCIDateTimeAxis type of the X-axis. So my question Is there possibility of skipping non-value period?

Hi, guys
Is there possibility to show tooltip by simply changing switch at the settings?
Not by tapping at the chart area as it implemented now.
Best regards,

I’m trying to create a spectrum viewer with your library. One important feature is a cursor supporting both automatic mode and manual mode. In automatic mode, it stays at the maximum value. In manual mode, it moves with finger panning. It’s close to the SCICursorModifier with the cross lines, but it should always stay on the plot even without touch. Also it should reside on real data points instead of anywhere in between like the SCIRolloverModifier instead of the SCICursorModifier.
Could you give me some advices about how to achieve it? Thanks.
EDIT: after reading more of your documents, I believe HorizontalLineAnnotation and VerticalLineAnnotation are the way to go. I have already added them as the automatic mode cursor. For the manual mode, I still need your help to achieve either:
1) a callback function for the VerticalLineAnnotation drag event, so that I could move both lines to the corresponding data point
or
2) a custom ZoomPanModifier to allow me to distinguish one point or two points touch: one point panning to move the whole plot and two points panning to determine the new cursor location and redraw the two annotations there
EDIT2: I was able to create a custom VerticalLineAnnotation class to handle the panning event. There is one more question left. Right now in order to update the verticallineannotation and horizontallineannotation on the graph, I remove them from sciChartSurface.annotations, change x/y locations and add them back. Is there a redraw or refresh or update function to call directly?
Thanks

Hello, I’m trailing your library right now. I’m wondering how to change the background color of the legend box. The document page for LegendModifier shows coming soon. I don’t see such option in LegendModifier definition in Xcode either. Thanks

Hello, I’m trailing your library right now. I would like to be able to move the graph around as well as a cursor on the graph. So I enabled both SCIZoomPanModifier and SCICursorModifier. But since both use one finger panning, the result wasn’t that good. Do you have any guidance for solving the conflict and letting them working together? I’m thinking to do it in the following way: if the touch location is within certain pixel range of the cursor, panning action will move the cursor, otherwise it moves the graph. Is it possible? Thanks

Hey all,
is there a way on iOS to export a SciChartSurface to a vector format in order to embed the exported chart into a PDF document? Right now the only thing I can find in the Documentation is exportToUIImage(). If not – any ideas for a workaround until such feature is implemented?

Hi, guys
My x axis is SCICategoryDateTimeAxis class type. And it’s limited by VisiableRangeLimit like:
[xAxis setVisibleRangeLimit:[[SCIDoubleRange alloc] initWithMin:SCIGeneric(firstItem – (lastItem – priorItem))
Max:SCIGeneric(lastItem + (lastItem – priorItem))]];
Also for scrolling my content inside chart:
SCIZoomPanModifier * zpm = [[SCIZoomPanModifier alloc] init];
[zpm setModifierName:@"PanZoom Modifier"];
[zpm setClipModeX:SCIZoomPanClipMode_ClipAtExtents];
Like a description SCIZoomPanClipMode_ClipAtExtents says:
“forces the panning operation to stop suddenly at the extents of the data” – but it’s not working constantly.
Sometimes it’s allow to scroll outside the range. Like on the attached image.
So my question is how to limit scrolling by min and max value?
Best regards,

I would like to format several lines differently while still scaling them all to the same YAxis. For example if one line needs to go out to 4 decimal places but then another does not need any decimal values at all i would like those formats to be represented in all of the tooltips with said formats.
