Hi am using high charts in my website and they are just awesome.I wold like to know whether there is any option to include variance in graph instead of the original values like the one in below snip.
instead of displaying the values of each bars i would like to display the difference between two.Is this possible?Thanks in advance
You need to enabled dataLabels for one series, and disable for second one. Then in dataLabels.formatter you need to compare values, and return value you want.

I need to create a histogram on Google Sheets, and I need it to have a log scale on the x-axis. This is because there are some random high numbers on my column, most numbers are clustered at the beginning.
The option shows up for the y-axis, but not for the x-axis. I think that when I was trying different options it showed up for a time...???? But now it just disappeared.
Please help!
Try normal chart (bar or line) and building a histogram table manually
Use FREQUENCY() formula for this. This way you can make your own classes the way you like and you can then make whatever chart you like.
Take a look at my solution - line chart with logarythmic y-scale.
X-scale as I see is unavailable for manipulation, but you can use own values and treat them as text.
Example dataset: 100 random values from 0 to 35.
Classes are powers of 2 (increase by 1/2 with each step)
Here is my example file. See if it helps

I am looking for a setting in Highcharts/stock that would allow me to apply a different format to displayed values of data, but not to the actual data as it is loaded into the series data. For example, we would like to plot y-axis data with precision up to 16 significant digits, and likewise, time values that use 6-8 sig figs. But that's not the precision we would like displayed in the tooltips, or other labels. However I am unable to find a way to format it without affecting both what is plotted and what is displayed. Here is an example of why this is a problem: let's say we have data points taken at .0001234s, .0001244s, .0001254s, and .0001264s, but we want to format the display of the time to ".0001" for all 4 data points. If we format it, then the "plotted" data ends up looking like it occurred at the same time-stamp, thus producing a stair-step look to our waveform.
I have looked at the custom functions that I can create to override tooltip display, but it doesn't appear that there is an easy way to make that very generic so that I can apply to all of the various chart instantiations (we use lots of different chart types), and that only covers tooltips; X-axis labels and Y-axis labels would also need separate functions for overriding those display values; there's possibly other places I haven't thought where the display might be affected as well. Is there any single, centralized place where the data points display value or format can be changed?
Example of stair-step appearance:

If you want to display various numbers (axis labels, tooltip, etc.) with various number of decimal places, you can use Highcharts.numberFormat function.
API Reference:
https://api.highcharts.com/class-reference/Highcharts#numberFormat
Example:
http://jsfiddle.net/eg0vepgq/
I have a simple column chart where the yAxis series data contains numeric strings in the millions and tens of millions. The chart therefore displays the graph numbers like this: "12.5M"(on the side of the grid) and in the points tooltip it is being displayed with a decimal point at the end. How do I make the data be shown in the thousands with commas? Will the chart be adjusted automatically to display more grid lines and raise the columns higher? Thanks a lot in advance.
I would have added an image, however it seems that that requires more reputation points. Sorry. Here's a link to it Screenshot
1) you can change the formatting of the axis labels by setting your own format with the formatter function
http://api.highcharts.com/highcharts#yAxis.labels.formatter
2) you can change the number of ticks by setting a tickInterval or tickPixel interval setting
http://api.highcharts.com/highcharts#yAxis.tickInterval
http://api.highcharts.com/highcharts#yAxis.tickPixelInterval
3) You can change how much extra space is added at the top/how many ticks there are, in part, by setting the maxPadding setting to 0
http://api.highcharts.com/highcharts#yAxis.maxPadding
When you have a small chart like the one you posted, Highcharts will often have trouble adapting its normal tick pattern, and you will often end up with just a min and max tick by default.
It's pretty easy to work these setting to get what you need though.
I have an area chart (and a percent-area chart) that uses timeseries data for the x-axis. The timeseries is missing some data points and I would like the functionality to be that of connectNulls:false.
Is there another HighCharts option or a way to extend HighCharts to add an option for this functionality?
I have looked at the docs and browsed the questions here on StackOverflow and Googled for it, but the solution that I have found is to use connectNulls:false and to insert NULL values for the missing data points, but inserting the missing data points with null values would be cumbersome in my situation and I would have to replicate it in a few places.
I would imagine that it would be possible since in the instances that there is a missing data point, HighCharts will maintain the x-axis spacing. All I would want is addition to noticing the missing data point and inserting the appropriate spacing to also use a y-axis value of 0/inset a NULL/the equivalent.
Thank you all for your time and assistance.
I have a kendo chart on my view that looks something like
You can see the x-axis label values overlap with each other because the series values too much. One solution is to increase the rendering space for the chart but in my case the UI does not allow increasing the space. How can I make this chart more bearable to the user?
Thanks
You can use:
Combination of steps and skip to remove some of the valueAxis labels.
MajorUnit to set different interval between major divisions.
