I have an application made of a "main" chart with stock quotes plotted in it and a "subordinated" one with some indicators; the two charts are dinamically feeded with data so they are ever moving and re-sizing their own YAxis accordingly. The following snapshot gives a better idea:
What I would like to do is to make the below chart XAxis exactly the same of the first one, so that it is possible to follow the evolution of the two indicators together.
Right now I'm doing the following work around:
With ChartBelow.ChartAreas(0)
.AxisX.Minimum = ChartAbove.ChartAreas(0).AxisX.Minimum
.AxisX.Maximum = ChartAbove.ChartAreas(0).AxisX.Maximum
End With
However this doesn't work well since the digits of the YAxis on the main chart are not always the same of the second one (as in the example above where it's 6-digits against 3-only).
Is there any way to aligne the two y-axes or make the X-Axis shared between the two charts?
Yes, as well as setting the Min/Max values, also set the interval and label interval values of the Axis.
ChartAbove.ChartAreas(0).XAxis.Interval
ChartAbove.ChartAreas(0).XAxis.LabelStyle.Interval

I have one question to the line chart.
I would like to create a line chart, which values are given. It should look like this chart here:
My question is, how can I implement this. I tried to put it as a stripline in the chart but it only shows a horizontal line without this steps at the beginning.
How can I create this line chart like in the picture above?
can I put into this:
the values.
Striplines are intended to display just a line across the chart, or varying width, height, to demonstrate an area... from MSDN
Strip lines, or strips, are horizontal or vertical ranges that shade the background of the chart in regular or custom intervals
To get the behaviour (I think) you require you can add a new series to the data you are returning with each of those datapoints. Irrespective of what other data you are charting, you can change the type of this series to Line Chart, and change the order of the series on teh chart to make it uppoermost.
Without further information - such as the data you are tyrying to superimpose this on - it's hard to advise further.
I'm not sure this is possible but thought this was the best place to ask.
Is it posible to get the position of a series value on a graph in excel?
For example, if I have a line graph in excel that has time along the x axis, is it possible to (using VBA) get the position of a specific point on that axis.
What I am trying to do is have a vertical line that is can be positioned based on a date entered by the user.
like this
Where the green line could be positioned by entering in a date (rather than just being manually moved) (or also it could be set to automatically move to the current date etc).
I was then thinking that if the position is on the graph is queryable, then I can just access the line object and move it to any position I wanted through VBA.
Any Ideas? or is this just not possible?
The "cleanest" way to do this is to add the line to the chart as a new series. In that way, Excel handles all of the positioning and your work is simplified. To get a vertical line on a chart, there are a number of options. I prefer this route:
Create a small 2x2 area with two dates and two values
Add in the date or x-axis value you want the line at (E3 in image). You can use =TODAY() here or some manually entered value.
Set the second x-axis value equal to the first
Use MAX and MIN on the data to get the values for each date. You can also use 0 and 1 and a secondary axis, but I think MAX/MIN is easier.
Add the data to the chart and format as a marker with straight line.
Formulas
E3: =TODAY()
E4: =E3
F3: =MIN(C3:C27)
F4: =MAX(C3:C27)
Result and chart data series for vertical line
I am using Microsoft.Office.Interop.Excel to create a chart. Some of my series in chart series collection are logarithmic, so I want to get hold of axis related a particular series, to set scale type to logarithmic.
Here is a way you could do it:
xlAxisValue = CType(xlChart.Axes(, Excel.XlAxisGroup.xlPrimary), Excel.Axes)
xlAxisValue.Item(Excel.XlAxisType.xlValue).ScaleType = Excel.XlScaleType.xlScaleLogarithmic
It is a generic example, if it is not working plese post your code.
I'm trying to get values (datalabels) of a columns polar chart INSIDE the actual column, and not on top of it. I've set inside: true property but it does not seem to have any effect, although it works pretty nicely while using a regular stacked columns chart for example.
Here is the fiddle showing the issue: http://jsfiddle.net/deurk/BeVyt/2/
Ideally, I'd like to have the datalabels in their "shares" if there is enough space, with white color. Does anyone have a workaround for this?
Thanks!
Indeed it looks like a bug, so I've reported it here https://github.com/highslide-software/highcharts.com/issues/1688
I'm trying to layout 2 linked charts, one above the other, similar to what you might see on the Google Finance page.
I can render both charts just fine, but getting the plotAreas to line up exactly is a bit of a mystery. The chart.plotArea.width of each chart seems to depend on the width of my Y axis labels. Thus the 2 charts are not the same width and have different values for chart.getCoord().l.
Right now, I'm using an offset which is manually calculated, but there must be a better way.
this.chart.render(); // top chart, getCoords().w=800
// manually set margins for lower chart to match
this.chartVol.margins.l = this.chart.offsets.l - 59 + 10;
this.chartVol.margins.r = this.chart.offsets.r - 31 + 10;
// render bottom chart
this.chartVol.render(); // bottom chart same width, getCoords().w=800
There are two simple ways to do it:
Use maxLabelSize and labelFunc. The former is the maximal label's size in pixels. The latter is a function, which takes a number, and returns a corresponding string label.
Use labels, which is an array of {value, text} objects, and include one long dummy string of desired size at the end with some bogus value.
I don't recall how to do it without custom labels, so if you feel like it is really needed, please submit an enhancement ticket.
