Strange behaviour of grid and AxisItems in pg.GraphicsLayoutWidget

[fscl...@gmail.com]

Hello,

I am making an application that adds plots from data selected in a QListWidget.

Each time that I press plot, a new subplot is added to the GraphicsLayoutwidget

I define the axis configuration in this function:

    def FormatAxis(self):

        global frVec3rdOct

        global frXAxis

        global frYAxis

        global rpmXAxis

        global rpmYAxis

        frXAxis=pg.AxisItem(orientation='bottom')

        frYAxis=pg.AxisItem(orientation='left')

                

        frXAxis.setLabel(text='Freq 1/3 Oct',units='Hz')

        frYAxis.setLabel(text='SPL',units='dB(A)')

        frXAxis.setGrid(255)

        frYAxis.setGrid(255)

        rpmXAxis=pg.AxisItem(orientation='bottom')

        rpmYAxis=pg.AxisItem(orientation='left')

        

        rpmXAxis.setLabel(text='Engine Speed',units='RPM')

        rpmYAxis.setLabel(text='SPL',units='dB(A)')

        rpmXAxis.setGrid(255)

        rpmYAxis.setGrid(255)

And each time that I add a nex plot I do it in this way:

            self.wm2=self.pg.GraphicsLayoutWidget.addPlot(row=1, col=0, title = 'Group 2',axisItems={'bottom':rpmXAxis,'left':rpmYAxis})

            self.wm2.addLegend()

The strange behaviour is:

- It appears two small axes in the corner of the plots

- In some of them the grid is plotted, In some of the dont

- Some liked axis stop working (not all!)

- In the plots in log format the plot is replotted on top when I change from one tab to other...

Any ideas??? Is a bug or I am doing somethinh wrong??

I just Read from an old post that the problem of the samll axis appering in the corner can be solved modifyint the code in plotItem.py line 170 as follows:

        for k, pos in (('top', (1,1)), ('bottom', (3,1)), ('left', (2,0)), ('right', (2,2))):

            if k in axisItems:

                axis = axisItems[k]

            else:

                axis = AxisItem(orientation=k, parent=self)

            axis.linkToView(self.vb)

            self.axes[k] = {'item': axis, 'pos': pos}

            self.layout.addItem(axis, *pos)

            axis.setZValue(-1000)

            axis.setFlag(axis.ItemNegativeZStacksBehindParent)

Does it continues being valid or have been updated?
