I have a gauge style high chart I am working on, and I cannot for the life of me figure out how to move the numbers on the dial inwards towards the center of the gauge. These are the numbers on the scale. How do I do this?
You can use offset parameter http://api.highcharts.com/highcharts#yAxis.offset with i.e negative value.

I am plotting data where all 3 piece of data for a data point are in the same units.
While the bubble size is correct relative to the other bubbles, I would really like it to scale with the horizontal axis ie for the data below, I would like the bubble to to measure about 30 units across on the x axis.
x(mm)
y(mm)
colour
bubble (mm)
Bubble 1
5
5
1
30
Bubble 2
10
5
1
20
I am pretty sure this is not a native behaviour, and I only need a rough visual match, rather than a fully accurate representation.
Does anyone have any ideas how to bodge this?
Thanks!
I have tried multiplying up the values to enlarge bubble size, but it seems that the size of the largest bubble is fixed
As I only require a visual approximation have also looked at using AppScript to create this (my coding is basic at best) but, while I can open a drawing canvas, there does not seem to be any way to automatically create a drawing from there.
I am having issues with my implementation of CorePlot. I have a subview in my UIViewController than contains the chart. Most of the data shows up fine but no increments / values are showing up on the y axis.
This is what I am seeing now:
If I shift the x axis start point by subtracting 10 (to better see the left half of the chart) I see this:
For the record, I do not have any values outside of the (positive x, positive y) quadrant on the chart and have logged out my data to verify this. Any input / advice would be appreciated, thank you!

This guy does a great job explaining that about halfway down... search for "You're Getting There!" to find exactly where he talks about the weird lines in the Y axis.
Hope this helps!
Set the leftPadding on the graph.plotAreaFrame to leave room for the axis labels at the left side of the graph.
The smeared y-axis is caused by too many tick marks and labels—they overlap and become illegible and negatively impact drawing performance. You need to adjust the labeling parameters to reduce the number of ticks and labels. By default, the axis draws major tick marks and labels one unit apart. The properties that need to be changed depend on the labeling policy you want to use.
I have two axis in highcharts and I dont specify the range for either. Please see graph.
For some reason, series one from 201 to 206 is taking up the whole chart while series 2 which is only -2k to 2k is being squeezed to the bottom, thereby extending the range all the way to 30k which is totally unnecessary. I think highcharts by nature wants to not have any overlap but I want that. What I'd like is for the right series to be centered, in fact I want the right axis to be centered at 0 always and can grow unrestricted in either direction. I can't hardcode any of these since I have no idea what the values could be. So Series 1 on the left is ok, but I want the value 0 for series 2 to always start at the middle of the chart. Any way to achieve that?
Try to set alignTicks as false.
I have a Highcharts bubble graph on my page and the top of one of the bubbles is getting chopped off because it is right at the top of the y axis. I've set the maxSize to 50% and would like to keep it that way. Is there a way to allow the bubbles to not have this overflow hidden sort of effect?
Without seeing an example I can only say to try adjusting the yAxis max value. That way there would be space to render your items. Or you can calculate your highest yValue bubble's radius and increase your yAxis by that pixel ammount in yAxis values.
So I have a simple line XY Graph with integer values on the Y axis and dates on the X axis. What I would be like to be able to do is do a horizontal two-finger pinch and adjust the range dynamically. Eg, pinching in would give you a bigger range (mental model being that you're setting the start and end date shown to be further apart) and then pinching out would give you smaller time window.
Is there some stuff built in for this already? Reasonably new to CorePlot and the default finger stuff just zooms the graph itself, none of the values.
Would I need to put a gesture recgoniser on it? or does coreplot have stuff build into it for this?
Cheers
This is how the built-in zoom features work. Use a plot space delegate to monitor changes to the plot space while zooming and make changes to the axis appearance as needed based on the changes. See my answer to your other question for more info.
