ngx-charts how to set the y-axis ticks width

I'm currently using the ngx-charts library to display some data.
One UX problem I found is, due to the length of the y-axis ticks change(f.e 1000 and 100000), the chart will flick before the redraw.
I'm wondering if there is a way to set the width of the ticks?
I've tried to add space to the ticks ( ), but it will display as 1000on the chart.
Anyone knows how to solve it?
UPDATE:
Click on the change button to see the flickering on y-axis.

How to show more x-axes in core-plot chart

According to our needs, we need to show the x-axis information at the top and bottom of the chart, how to show more x-axes? THX
Several of the Core Plot example apps show how to add multiple axes in a graph. See, for example, the "Axis Demo" in the Plot Gallery app. Position one x-axis at the top and the other at the bottom using the axisConstraints or orthogonalCoordinateDecimal.

HighStock - Issue with dynamic charts when navigator is disabled

I am using the dynamic chart of Highstock. I happen to disable the navigator control of the chart, but have the scrollbar enabled. Now the issue is - if I zoom the chart once, the lines that are already drawn for the curves start to get deleted/erased starting from the left side of the chart and after a certain amount of time all the lines of each curve on the chart get deleted. But if I enable navigator control for the chart, this issue is not see.

Dynamically creating multiple chart areas

I am creating a program which given some data files, creates charts based on these files. Rather than creating multiple charts, I have chosen to create multiple chart areas in a loop and add the various data to the chart areas. When using some sample data, which is small, the program creates 3 chart areas within a chart and works fine.
However using larger data, the program creates the chart areas but because there are over 10 chart areas to create, they do not fit into the size of the chart and also are aligned vertically rather than horizontally.
What I would like to do is increase the size of the chart fitting in all the chart areas for large data, aligning all the chart areas vertically and allowing the user to view all the chart areas via a scroll bar, since there will be a lot of chart areas using the real data files, any help will be appreciated.
The below are examples of alignment types you can switch to
Chart1.ChartAreas(0).AlignmentOrientation = AreaAlignmentOrientations.Horizontal
Chart1.ChartAreas(0).AlignmentOrientation = AreaAlignmentOrientations.Vertical
As for a scroll bar, the chart control doesn't support scroll bars. What I would do is have my original chart contained in some sort of panel/tab [any container that supports scroll bars] and then is number of charts required reaches a certain level add another chart below your original and then allow the container to build the scroll bar
'when charts required is now 5 create new chart
If Chart1.ChartAreas.Count =4 Then
Dim OverflowChart As New Chart
'add a new chart below your current chart and let the container
'have the scroll bar and not your chart control
End if
I managed to figure it soon after I posted here which is ironic. For the sake of anyone with similar problems in the future. The way I did it was to:
- Add a scrollbar to the form
- Make the blank chart as big as possible to fit whatever data which was going to be used
- Manually set the position of each chart area using ChartArea.Position and changing the posY for each chart in a loop
This worked great and gave me a lot of control as to how big I wanted the chart areas since ChartAreas.Position also has a width and height attribute and allowed me to easily align the chart areas horiziontally using the y coordinates of each chart area.

How do I add labels to individual bars on a bar chart using Dojo charting

Can the bars on a Dojo chart be labelled with the value? I have the tooltips but I would like the bar values to be shown all the time and for when the graph is printed.
Also I have some bar charts which can run over several pages. When you print the charts, it will just cut off when it reaches the end of the page.
Is it possible to print the x axis at the bottom of the page for each page break?

Not yet. See http://trac.dojotoolkit.org/ticket/11366
