I want to ask, i am making a php program (graph) using highcharts.
What I want to ask is how to swap series1, series2, series3, to 0,1,2,3,4.
How to change its position.
example code :

I need to show a graph in my iOS app something like
We have been using CorePlot for all the graphs and now I need to add a new kind as shown above. I found I could draw a graph like the above with CPTRangePlot. My problem is I can only draw a horizontal graph as shown below.
Is there any way to make it vertical? For a single curve we can easily do that by switching the value on X-axis and Y-axis. But for this kind of "range plot", I could not find a way to make it work for drawing the upper-bound and lower-bound lines and filling range with color can only be achieved on a normal horizontal graph. And yes, I can easily rotate the container view by 90 degrees, as I did in my testbed app. But I just cannot do this in our current app because this new added "range plot" graph is not the only one on the view. We have many other curves sharing the same plot space. So is there any hidden property or method to achieve the job? Thanks in advance!
I just added a fillDirection property to the range plot to enable this feature. You'll need to use the latest code from the release-2.3 branch.
I'm drawing a chart in an iOS app and I want the gridlines to start in the x axis but end in the data point instead of extending all the way up to the top.
Is this possible?
Thanks in advance.

The shinobicharts framework doesn't currently support this as an out-of-the-box feature.
A workaround may exist though. You may be able to add your own gridline subviews by using the SChartAxis method pixelValueForDataValue: to work out where in the plot area coordinate space you should draw your vertical line up to for a given data point.
Once you have your coordinates there are various ways you could draw your gridlines:
Add a canvas view behind or in front of the chart (depending on what effect you want). Then use your coordinates to draw your gridlines using CoreGraphics or some other drawing technique.
Create individual UIViews that each represent a gridline using your coordinates and add these behind or in front of the chart.
One thing to be aware of with this technique is that the gridlines will not automatically update when you pan and zoom. In order to do this you will need to override one of the chart's delegate methods that notify you of range changes and update your drawn gridlines to match the new data point positions.
Another potential workaround could be to use a column series to mimic gridlines. If you create a column series and feed it the same data points as your original series this will result in columns that go up to the y-value of each data point. You could then use the property interSeriesSetPadding on SChartAxisStyle to cause the columns to appear very thin.
I hope that information is useful!
Does highcharts support phase change lines ? It may be called multiple things but im looking to see if an X axis delineation line can be drawn in highcharts. It is used to specify a specific date in time where something in the environment changed. The chart reader would then look at that line and see if that change to the environment impacted the data represented by the lines in the line chart.
Anyone know if this can be done with high charts ? Sample image attached.
Great answer from Ondkloss: http://www.highcharts.com/docs/chart-concepts/plot-bands-and-plot-lines That page shows exactly what I was looking for.
Is it possible to change the plot line from some specific point. One way around is to create two series and plot them on chart them. But we want to change the plot lines from specific point without using two series.
I want to make a multiple plots with the x-axis aligned so that we can compare two set of data. I want it to look like this

In my case there are some addition requirement that some of the plot are lines and some are bar. So the default scale does not align even if the data range are the same.
I found some good suggestion about "stacking" the charts. It is a little bit complicated but a promising way to try.
https://stackoverflow.com/a/12179023/229075
However I also have other use case that may push the envelop of simple stacking. For example, I'd like to do scatter plot matrix sometime when both x-axis and y-axis have to align like this

Rather than putting many chart in one Highchart, this may requires have many separate charts but have better control in how the axis is layout.
If you want to use one one chart, you can use linkedTo option to connect axis.
If you want more simple charts, you can manage to connect axis using event afterSetExtremes, where you can call setExtremes() for another chart.
