Problem with X-axis scrolling with custom datafeed

[Yachter]

Hello,

I'm having trouble with scaling after using my data.

complicated2.py:
http://www.fileconvoy.com/dfl.php?id=gd499040d809ca23910003808265806a0b8efaa4d75

Also, I tried to adopt other examples, like embed.py, but get similar problems:

Appreciate any help.

You have your timestamps in the reversed order. Do df = df.sort_index() to fix.

Thank you very much. One question more:

How to turn off both lines for Stoch indicator ? Probably it's some bug in complicated.py example.

[highfestiva]

Write some code of your own, as of now that viewbox can be hidden/shown, no further detail is available in this example. It is not a trading tool, it is an example.

Just run the original complicated.py, select 'moar indicators', and turn off RSI and Stoch as shown in the picture.

Btw, you've made a really brilliant financial charting library, nothing comparable to existing in the python world, trust me & congrats, man. I'm using app shots in my postgraduate research reporting on financial markets, and really thankful. It would be valuable if you consider some of my suggestions and remark to make the app better.

There're some of the things that are unclear to me. For example, in my application, I'm trying to adjust the range of the Y-scale to fit
a new rectangle, because it is outside of data's value range, so make that rectangle visible:

`y_min, y_max = ax.axes['left']['item'].range

ax.axes['left']['item'].setRange(y_min, (rectangle_Y_max * 1.10))

fplt.refresh()

rect = fplt.add_rect((rect_time_start,rectangle_Y_min), (rect_time_stop, rectangle_Y_max), color='#0f0f27', interactive=False)`

this is code I placed at the end of the callback function of QComboBox, but it does not change the range of main candle chart.

[highfestiva]

Change to this: plots['stoch_s'] = fplt.plot(data['stoch_s'], color='#650', ax=ax_rsi, legend='Stoch sig') to be able to uncheck visibility.

Try finplot.set_y_range() for visibility instead.

[Yachter]

Only finplot.set_y_range() works, but that's fine.

So need your advice: is there a callback function for the AutoZoom feature,
so be able to set the scale and make visible all objects do I need to see?

Another question related to that what is alternative for Y-viewport scale
similar to X-axis fplt.set_x_pos(xmin, xmax, ax) function ?

[highfestiva]

No. You might try ax.vb.set_range(x0, y0, x1, y1).
