I wonder if HighCharts provides a way to get the length of a curve plotted along the serie of points in a x,y chart.
Do you think I can achieve this in highcharts?
I have dataset with 3 variables: X,Y and Date. I need to plot on a X Y chart the variables X and Y, but also I would like to present the date as gradient on the line. For example, if the series has a green color assigned, the oldest point in the series would be set to a light green and the most recent a dark green.
Thanks.

Question 1: Can we create a bubble chart with x-axis aligned vertically and opposite to y-axis as in below image.
Example
Question 2: Dual y-axes are possible in highcharts but a series data can be associated to just one y-axis, is it possible to associate a data series with both y-axis? In other words, data points plotting will be in respect to 3 axis: x-axis and dual y-axes.
I cannot find how to do this for a while now, my graph is drawn ok every time but I want to move up my graph, like when you have f(x) + n. So, what I want to do actually is change Y origin, so I can draw my (x,0) points. I do not want to draw my points on X axis, I do not see the line that good. I want that my zero Y point actually starts at point three, but not to transform the graph at the same time. Here is picture of what I want to do (see the green line and Y point):
The plot space yRange controls the range of data visible. The image in the question looks like it has a location of negative one (-1) and length of 18. You can use the axisConstraints to keep the x-axis along the bottom of the plot area. If you don't want to use constraints, set the orthogonalPosition to the location of the yRange.
I have a Highcharts scatter plot with a datetime x axis. The x values are all in the past. The y coordinates are positive integers, typically in the range 100..10k. I want to draw lines from the imaginary point (tomorrow, 0) back to some of the data points.
The Renderer's path command looks to take absolute coordinates in chart space. How do I transform the point (tomorrow,0) into those absolute coordinates?
Also, assume the data was from 1995..2005. The default auto-scaling of Highcharts would make tomorrow be off the chart to the right. What will happen when drawing the path? Will the chart remain the same scale and the line be clipped at the right-hand edge? (That would be OK). Would the chart be redrawn with a new scale so that the x axis covered the whole span from 1995 to tomorrow? Something else?
Thanks in advance...
Found it. There is a translate() function to do the conversion. See the Highcharts support forum thread for info on the function.
Use Axis.toPixels() and Axis.toValue()
