Hi Bryan,
I have tried to update dynamic plots on gridplot object from the browser, but I can’t able to add a new plot on to column of the gridplot object, could you help me with this?
Code:
Hi,
There is not enough information below to speculate. I'd be happy to look at a small *complete* runnable script of what you have tried.

Hi Bryan,
Sorry for the inconvenience,
Here I have attached the detailed code snippet below.
main.py
trade_names = [‘COPPER19APRFUT’, ‘GOLD19APRFUT’]
Plot Configuration
indicators = {‘RSI’: {‘y’: [‘RSI’], ‘plot’: ‘line’, ‘title’: ‘RSI’},
‘MACD’: {‘y’: [‘EMA12’, ‘EMA26’, ‘MACD’], ‘plot’: ‘macd’, ‘title’: ‘MACD’},
‘Heiken_Ashi’: {‘y’: [‘OPEN’, ‘CLOSE’, ‘HIGH’, ‘LOW’, ‘COLOR’], ‘plot’: ‘candlestick’, ‘title’: ‘Heiken_Ashi’}
}
Attached this Code Below

def update1(step):
pass
def update2(attr, old, new):
for key, value in indicators.iteritems():
curdoc().remove_root(p[old][key])
curdoc().add_root(p[new][ci])
def update3(attr, old, new):
global cts
print(grid)

grid.children[1].children.append(p[cts][new]) #<---- This line is not updating the plot on the browser
global cts

cts = trading_symbol.value
ci = ‘Heiken_Ashi’
trading_symbol.on_change(‘value’, update2)
indicators_.on_change(‘value’, update3)
curdoc().add_root(trading_symbol)
curdoc().add_root(indicators_)

Hi,
This is really far too much complicated code. I was suggesting you craft a very minimal/simple example that illustrates just the issue with nothing extraneous or unrelated included. That said, I did still try to run it but was unsuccessful:
* it's python 2 only. I made a few changes to allow it to run on python 3. Please be aware that Bokeh will drop python 2 support entirely later this year
* Even after fixing up for python 3, it it was not complete. It is missing all the relevant imports. At this point I stopped trying.
If you can provide a *complete* *minimal* single script that is runnable as-is, without any modification, I will take a look.
Thanks,
Bryan

Hi Bryan,
Thank you for your quick support, I will soon ping you back again with a small working piece of code about this issue.
Thank You,
