I have created a bar chart using Core Plot (1.1) and would like to plot all data labels above their bars.
Problem: There is no data label shown for the bar with the negative value.
Question: How can I plot the data label plotted for the negative bar on top of the bar?
Thank you!
I don't think there is an easy way to do this. You could suppress the labels for the negative bars and draw them yourself using plot space annotations.

In my react-native-chart-kit pie chart, there will always be either absolutely no data (which I won't show the pie chart at all) or there are exactly two pieces of data. By default, the legends are showing to the right of the pie. The actual text in the legend is coming from the name properties in data. I have tried putting in a newline character (i.e. \n) but that didn't help. So, is there a way to wrap the text in the legends to show in two lines? Or can I change the position of the legend to right below the pie?
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.
I've set up a core plot graph with two plot spaces - one for a set of bar charts, with its y-axis on the left, and one for a scatter plot with its y-axis on the right. It works, except that the grid lines don't match up:
Both axes have their labeling policy set to CPTAxisLabelingPolicyAutomatic. Is there a way to change the axes so that the grid lines match up?
Not with the automatic labeling policy on both axes. You could keep the automatic labels on one side. Read the tick locations and use that to decide what plot range (yRange) and tick locations to use on the other side so they match up. If you allow the user to change the plot range outside control of your app (e.g., by scrolling and/or zooming), use a plot space delegate to monitor changes and update the secondary axis labels as needed.
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?
Can the bars on a Dojo chart be labelled with the value?
Not yet. See http://trac.dojotoolkit.org/ticket/11366
I am unable to set the label name exact below the bar of bar chart. How to change its origin value to move right side so that it will be exact below of the bar. Please find the image here in this link: i.imgur.com/kJEeM.png
I am search for solution, yet I did not get any solution please help me out of this....
You should use axis labels on the x-axis. There are several example apps included with Core Plot that show how to format dates on the axes. If you already have the text of the labels, you can use custom labels instead. There are examples of that technique, too. The linked image doesn't show an axis line--just set the axis and tick line styles to nil to suppress drawing the axis line.
