I'm having some issues with Windows charts and the points displayed on the x-axis.
I have two plots of data in a line chart based upon set data points, e.g. 200,400,600,800,1000. I also use a 3rd & 4th series to colour areas depending which line is higher. To do this I've had to add extra points where the two lines intersect. This then throws out the labels on the x axis as the chart automatically labels the points something odd such as:

|

=========================
120......370.....590.....730......850
Is there a way I can explicitly specify the datapoints on the axis that I want to use, other than the min-maximum value function?
So you want to customize the X axis labels to match your data? If so you can define custom labels and a customize event to do that. This was posted on StackOverflow by the user Somebody

My questions:
How can I remove these numbers that I marked in the screenshot https://prnt.sc/116tvvz?
How do I specify the range of numbers on the chart? For example, here's a screenshot https://prnt.sc/116txqs. It shows numbers in the range of 50.000-60.000, but the graph starts from zero to 60.000.
I'm assuming you're using the default WinForms Chart available from the framework? (from System.Windows.Forms.DataVisualization).
If so, you could manipulate the X & Y axes either from code or from the UI. The key is that they're defined under ChartAreas.
From the UI: Properties > ChartAreas > Axes. From there you can hide the labels by turning off Enabled. Same with Minimum and Maximum, and a whole lot of other customisations.
They're obviously also available from code, which can be useful in case you want to play with the scaling at the arrival of each data point.
More reading on the ChartArea class in the docs.
In my WinForms project I use the standard Chart control (from the VS toolbox) to display pressure versus time. It must be possible to zoom the graph. This works fine, but the X-axis values in the zoomed graph shows the values in a lot of decimals:
Does anyone have an idea what I can show the values in a better format? For example, in the above graph I would see labels like: 8.00, 10.00, 12.00? I can also live with values like: 7.98, 9.98, 11.98, so with a limited number of decimals.
I've looked in the control designers for the Chart control where I can specify a format string or the number of decimals, but I could not find it.
There is nothing special for this chart. It shows 2 series (not easy to see but you could probably see a blue and a green line). I use for both series the FastLine type of graph. I enabled the zooming by setting IsUserEnabled and IsUSerSelection to true for CursorX and CursorY in the graph designer. As said, this works, but I could not spot a property to customize the format of the values.
Set the LabelStyle.Format property:
chart1.ChartAreas[0].AxisX.LabelStyle.Format = "0.00";
Or
chart1.ChartAreas[0].AxisX.LabelStyle.Format = "{0:0.00}";
I am creating a web application using c#. I have four values(or series) volt,current,wh and temperature which I will have to plot in a chart control against time which(time) will be shown in x-axis. All things done correctly. But the range of the values are different like one is in range of more than 1000,another lies between 0 to 10,another shows negetive value,etc. I want to create different y-axis for each series.I had created two y-axis which is a property of series(YAxisType),primary and secondary. Is it possible to create multiple y-axis?I had searched in google but didn't get any proper answer. Please help me.
You can only use 2 y-axis(primary and secondary)
But you can create a few chart areas within one chart control
Or you can add a button that will hide one chart control and show another(with others 2 axis)
I am able to create bar chart and displaying strip line through MS Chart below snap:
Same chart I am trying to create in C# at run time feel like to export the chart in excel. Can anyone guide me how can draw the Strip line on bar chart OR can combine bar chart line chart so line chart seems displaying the strip line.
one possible approach is to add a new series like this:
add a new series to the bar chart, using 2 cells equal to the value where you want to have vertical line (x column in illustration)
select the new series bars and change chart type to X Y (Scatter) - the one with both markers and lines so you can then select it again
edit data range for the new series, so x-values point to your value and y-values to 0 and 1
change the right axis to Minimum: Fixed 0,0, Maximum: Fixed 1,0 and change major tick lines and axis labels to None
remove markers and change line style
How can i add labels for each and every yvalue in series of a rangebarchart ?
You all know that for plotting rangebartype series ,we need two yvalues as yvalue[0] and yvalue[1] .Here I need to add data labels to each of those yvalues( which means both at yvalue[0] and yvalue[1]).how can i implement that?can anybody suggest me?please!!
The label should look like as below for a rangebar(to be displayed on both sides of a rangebar).
Label1 ███████████████ Label2
Label███████████████████ Label
There is no built-in way to do this in MS Chart. However, there is an ugly little workaround that will give you the display that you want.
For each datapoint (rangebar) that you want to display, you will need to create 2 datapoints that lie on top of one another. As an example:
DataPoint0: X=1 Y=5,10
DataPoint1: X=1 Y=10,5
These two datapoints lie right on top of one another, except one is displayed left-to-right and the other is displayed right-to-left.
For each DataPoint, under CustomProperties, there is the BarLabelStyle property. Set this to 'Outside' for both of the datapoints. Normally, this will display the label to the right of the range bar, but for DataPoint1, with the reversed Y values, the label is now placed to the left of the range bar. So, set your label for DataPoint0 to 10 (max value), and for DataPoint1 set the label to 5 (min value).
This will then look just like one range bar with the min value on the left and the max value on the right.
Caution: If either end of the range bar is too close to the edge of your graph, MS Chart, in its infinite wisdom, will force the label to be displayed inside the range bar. To overcome this, you can actually add a third number to the Y values of the DataPoint object. This third value is not displayed, but if it is larger than the largest Y value in your data series, it will force the chart to rescale to accommodate this larger value, so your labels are not forced inside the range bars. You could probably handle this another way with setting properties of the ChartArea also.
