I'm using DOJO column charts in my application. Here i have a requirement to display the value on top of the bar. That can be achieved using the label property. After doing this i had another problem i.e. If the value is large then all values are getting overlapped as shown below
In order to overcome this overlapping issue i was trying to display the label in vertical direction. Can you guys help me solving this issue
You can rotate the labels using the "rotation" attribute when you create the axis
For example:
chart.addAxis("x", {labels: xLabels, rotation: 90});

I was building a chart in HighCharts with logarithmic axis type. Here is a link to the code in JSfiddle.

I'm consuming data from Google sheets and at the moment, the values are plotted exactly as in Google Sheets. I however wanted to plot the changes over time instead, something similar to this image. Ignore the left percentages (labels), the ones on the right are the workable ones or rather where my focus is on.
I have tried applying the plotOptions and specifying the compare: 'percent', but still I get the chart not showing the change over time but the exact stock value instead. Is there a way I could get the percent changes instead of the values themselves? I will appreciate any assistance. Thanks!
I am displaying some visualizations using Google Charts.
There is great variance in the data so some large numbers co-exist with small ones. In the case of a Column Chart this results in a scaling whereby some of the small values probably compute to less than one pixel of height and are thus invisible.
As a result there is no area to hover above, so I cannot show a tooltip.
Is anyone aware of a way to show a tooltip in this situation?
How about the white space above columns? Is there a way to include that as part of the hover region? I cannot find info about this in the Google Charts documentation so it is unlikely, but maybe someone is aware of a way...
By using the option focusTarget: 'category', you can achieve this. It's mainly used for displaying multiple values from the same "grouping" at the hAxis, but it fulfills your needs for this as well.
Example
Currently I am facing issue while rendering chart for large data in EXT JS. Chart gets cut or overlapped.
For example, I have 500 names on x-axis to plot then chart displays only 15 to 20 of them and others get cut. According to my view there should be scroll bar to view whole chart rather cutting the legends. I have tried to found solution for having scroll bars for such large charts but I am not able to find it.
Any other way for viewing whole chart is also accepted.
One workaround I can think about is 'panzoom' interaction.
Please visit link given below to see an official example with 'panzoom'.
http://dev.sencha.com/extjs/5.1.0/examples/kitchensink/?charts=true#line-markers
With 'panzoom', you can zoom in to the chart and then scroll/pan. Zooming in to the chart would make the hidden coordinates visible.
It may look like this because you might have smaller space to render the chart as your data is too big. So you can try with 'pan zoom'. But I don't think so you will get a useful chart. It will still get junked.
I have tried using all sorts of combinations of tickInterval, tickPixelInterval label formatter and tickPositioner and I haven't been able to solve this issue.
I have a chart builder that pulls in different feeds and allows the user to modify the date range of those feeds before shooting this data into highcharts and spitting out the chart.
The problem is that some of the time, the first and/or last dates get cut off. Here is an example:
Without adjusting the margins of the chart (which causes the chart to take up less space), how do I prevent this from happening?
If I was able to determine the pixel location of the ticks and their labels, I could in theory, hide the specific ticks and their corresponding labels which were located outside the graph / cut off. Thoughts?
Without looking at your code - there are a few things you can do.
Rotate your labels
Play around with the x/y axis labels
Align them to the right
Hopefully one of these would help your cause.
Hi i wonder if it's possible to disable the automatic scaling of a highchart.
Or is ist possible to set a fixed position and or width and height to the labels ?
Here is an example, this is how i'd like to have my chart look like.

But if the labels have a different length highchart shrinks the graph.

Has anybody an idea how i could fix this?
One way to solve your problem is to use a different series to display the labels. In this example I use a second scatter series to display the labels. To position the labels just set the y value. I set the color of the points to the same color as the background to hide them. Then I use the dataLabels formatter to display the labels how you want them.
