I am having problem in plotting the timeseries chart in highcharts
exmaple
12/05/2012 - 100
12/01/2012 - 200
12/15/2012 - 300
11/01/2012 - 400
when i plot chart its order of printing is based on order of data points
but i want to plot the data time wise i.e 11/01/2012,12/01/2012,12/05/2012,12/15/2012
While plotting th chart its gets printed in zig zag manner instaed of trend line.

Time based data needs to be in chronological order starting from earliest date.

How can I plot a pie chart without including the NaNs that are present in the column of interest?
Use =filter(A2:B, not(iserror(B2:B))) to omit rows that show NaNs. Then insert a chart that uses the filtered results as its data range.
I am trying to plot three time-series data from csv in a single chart using highcharts. Before plotting the data I am normalizing the data so that all the three data sources plot data which can be easily compared for a given range.
But when I use the tooltip I want to show what the original value of the data is in the tooltip on hover.
I looked at the tooltip formatter but could not get through for changing the value for only one of the data series.
My weather station collects every 15 minutes the current temperature. With Highcharts I created a chart to display the last 24h. So I pass all the 96 quarter-hourly values to the chart. This looks not so pretty. Instead I would just display the average of each hour.
Is it possible to display the average value for each hour based on a series of quarter-hourly values and leaving the calculation to Highcharts and not doing it myself?
You can use highstock which allows to use datagrouping.
I was trying candlestick chart using highchart ( highstock ) and find out that when I increase/decrease Navigator in candlestick chart the width of candlestick get changed. Sometime it display high, open, close and low for one hour interval whereas sometime it is displaying for month. I would like to grab these dynamically changed candlestick width ( not the pixel width but the real time interval) and display them in the chart title. Is there anyway I can get these information and update them dynamically in chart subtitle?

Thank You
What you are seeing are the effects of plotOptions.series.dataGrouping (API Reference) where the data is grouped and values are approximated to display the data faster. If you look at the example for units on the above linked page you'll find that you can determine and set what those groupings are. The grouping isn't truly dynamic, it's predefined.
I created Highstock chart with 3 series,
some of the series have missing data in some time interval.
what the Highstock does is "complete" or "connect" the points to each other but I want it to plot no data in those intervals.
how can I do that?
I tried to set the xAxis intervals but it did not work.
here is some basic example from thewebsite.
Example from highchars.com
in this example it does what I want - you can see that there is points which are not connected.
Look at the 'connectNulls' property:
