Hi,
I am working with PlotWidgets for my project. I need to be able to copy and
paste charts. For this I make use of the export functionality. I was able
to copy-paste charts previously but now it shows the following error (when
I click on copy):
Traceback (most recent call last):
File
"C:\ProgramData\Anaconda2\lib\site-packages\pyqtgraph\GraphicsScene\exportDialog.py"
, line 136, in copyClicked
self.currentExporter.export(copy=True)
File
"C:\ProgramData\Anaconda2\lib\site-packages\pyqtgraph\exporters\ImageExporter.py"
, line 70, in export
bg = np.empty((self.params['width'], self.params['height'], 4), dtype=np
.ubyte)
TypeError: 'float' object cannot be interpreted as an index
Not sure why this error is coming even if the width and height params are
int.
Does anyone know what is the reason for it? Shared the Sample code below:
w2 = pg.PlotWidget()
w2.addLegend()
axis2 = daxis.DateAxisItem(orientation = 'bottom')
axis2.attachToPlotItem(w2.getPlotItem())
idx2 = abc.index[lookback2+1:]
df2 = pd.DataFrame.from_dict(idx2)
timestamps2 = list(pd.to_timedelta(df2[0]).dt.total_seconds().astype(int))
w2.plot(x = timestamps2, y = list(100*abc.iloc[lookback2+1:]), name = "ABC",
pen = 'b')
w2.plot(x = timestamps2, y = list(100*def.iloc[lookback2+1:]), name = "DEF",
pen = 'r')
w2.plot(x = timestamps2, y = list(ijk.iloc[lookback2+1:,0]), pen = 'r')
w2.setLabel('left', 'ABC', units='%')
w2.setLabel('right', 'DEF', units='%')
self.ui.verticalLayout2.addWidget(w2)
