Axis label and units prefixes

[Leonid Rumatov]

Here is my wish.

It's not urgent, but, I think, everybody need this.

We can set label to the axis, including measure units.

And, the pyqtgraph itself choose prefix for the units - 'k', 'm' (means - 'kilo', 'mega') and so on.

But, if the library do so, then tick labels on the axis (that show numbers) have ti be divided to this koefficient.

If axis choose prefix 'kilo', tick labels shoud be divided by 1000, if axis choose 'mega' - to 1000 000.

Now I can do this myself, but, I think, that will be correct.

I think what you are describing is already the default behavior if you specify units for an axis. For example:

    plot.setLabels(left=('axis title', 'm'))   # scaling will automatically add SI prefix

Hello, Luke.

Yes, you right, that was my mistake.

Small linked question.

How can I turn off coefficient on the axis label?

Coefficient != 1.

I think AxisItem.setScale is what you want:

    plot.getAxis('bottom').setScale(1)

Hi Luke,
a small question. I am using plotitem and the x axis shows 'ks' kilo second, which I don't want. I want my axis to show 1000(s) after 900(s) instead of 1(ks). How do I disable this thing.
Do I have to change something here?
p1.setLable('bottom', "Time", units = 's')
