ANSWER

The problem is you are calling make_addplot() with only one data point at a time. There is also no need for the date index in the make_addplot() call; only the data.

Also, the length of data (number of rows) passed into make_addplot() must be the same as the length (number of rows) pass into plot().

make_addplot() should not be within the loop.

Try replacing this part of the code:

callback in dash/plotly ignores if condition

Asked 2022-Jan-07 at 07:40

I am running into an issue with dash/plotly. I have an html page with an Input box, a button and an area for a graph. I used a callback to update the graph (based on the input box entry) once the button is pressed. However when I load my page for the first time, it seems plotly is forcing the evaluation of the callback function although the input box is empty. Hence I get a "callback error updating...".

Here is my code:

...

ANSWER

Answered 2022-Jan-07 at 07:40

My idea was to have the graph area being updated or drawn only when the button is clicked. This works fine after the first call but not when loading up the page for the first time.

If you want to avoid a callback being executed on page load you could set the prevent_initial_call attribute of the callback to True.

All of the callbacks in a Dash app are executed with the initial value of their inputs when the app is first loaded. This is known as the "initial call" of the callback... You can use the prevent_initial_call attribute to prevent callbacks from firing when their inputs initially appear in the layout of your Dash application. This attribute applies when the layout of your Dash app is initially loaded, and also when new components are introduced into the layout when a callback has been triggered.

Changing array string inputs to integer inputs not working

Asked 2021-Sep-15 at 05:31

For a project with Cryptotrading I'm trying to make my own scanner. First I collect data and append them to a list. Then I convert the list to a np.array. This array then has strings as inputs but I need to change them to Integers. When I print the np_closelist it gives all the desired values, but in an array with strings. When I try to print b (so the converted np_closelist to integers) it doesn't print anything. When I try this method in a different file with easy values it does work. Could anyone help me figure out how to fix this? Thanks in advance!

It's normal, you shouldn't use pip to install python3 libraries, use pip3 instead, pip is for python2. Probably what happened is that you installed ta-lib for python2(that use pip) instead of python3(that use pip3).

On posted printscreen you have shown IDE. To be clear, PyCharm is not your python programme. You should run you python code in console. In this case 20 consoles (cmd). Moreover, PyCharm sometimes needs a lot of RAM and its completely normal.

If you have Windows OS you can try to run python code in cmd. Just type inside cmd window:
