Hi,

I have been trying to get the user input from the user and trying to put it into the plot with a button click or so but I am not able to do that. Also I want to update the point values in the plot with the user given values. I tried various things like CustomJS and callback but it did not worked for me. Can anyone help me with this?
I will be really thankful.

Many Thanks,
Sandy

Hi Sandy,

This is pretty general and non-specific, it’s hard to give any concrete guidance. Can you provide more details, e.g. what sort of data is to be input, what kind of user interaction you are looking to have, and what exactly you have tried so far?

Thanks,

Bryan

Hi Bryan,

I have a plot for parameters say x and y with few other parameters a,b and c. I want the user to input values for all the parameters on a browser and with a click of a button it should plot the newly added point in the plot on the browser itself. I used TextInput to get the input from the user and also made a button to update the plot but I am not able to achieve it. I need assistance on this one.

Hi Jean,

Thanks for your time, I appreciate your help.
I am exactly trying to do what you have written in the code but unfortunately the point that is being added from the inputs is not permanent, it gets vanished after page gets refreshed. Is there any way to put the input permanently in the plot?
Also I will be really thankful if you can tell me whether is it possible to delete points and modify the parameters of a point from the plot by writing CustomJs for Taptool?

Really Thanks for your help.

    I have a plot for parameters say x and y with few other parameters
      a,b and c. I want the user to input values for all the parameters
    on a browser and with a click of a button it should plot the newly
    added point in the plot on the browser itself. I used TextInput to
    get the input from the user and also made a button to update the
    plot but I am not able to achieve it. I need assistance on this one.
    Tell me if you want more specific explanation.

    Many Thanks,

There is not really any way to persist information like that in a static web page.

If you want something like this, you will have to take steps to make sure the data is persisted elsewhere (and also re-used by the plot). There are a couple of possibilities I can think of:

* use the JS callback to send data to some server that has a REST API that can store the data in a database or whatever, and probably use AjaxDataSource to pull the current most up to date data from the REST API when the plot is loaded.

* Use a Bokeh server, and have the python Bokeh Application code store things in a database or whatever (you would not use JS callback in this case, you'd use python server callbacks). This approach could range from fairly simple if there is no concept of "users" or different states/data for each user, to very complex, if you need to deal with users, authentication, having different views depending on the user, etc. You can find a more in depth example involving those sorts of things here, for reference:

  https://github.com/bokeh/bokeh-demos/tree/master/happiness

It occurs to me there might be a third possibility:

* use the JS callback to store data in a cookie. I'm not sure if this is a good or bad idea, or really how to go about it (maybe others do). Also there's not currently any "on load" lifecycle hook for a Bokeh plot, so it would probably also involve writing a custom extension to Bokeh to accomplish, as well.

Thanks,

Bryan

Hi Jean,

Thanks for your time, I appreciate your help.
  I am exactly trying to do what you have written in the code but unfortunately the point that is being added from the inputs is not permanent, it gets vanished after page gets refreshed. Is there any way to put the input permanently in the plot?
Also I will be really thankful if you can tell me whether is it possible to delete points and modify the parameters of a point from the plot by writing CustomJs for Taptool?

Really Thanks for your help.

Hi Sandy,

I'm not sure exactly what you're trying to achieve here.
Anyway, here is a working exemple. I hope it helps.
- you need to add your textinput and button to the plot to display it
- callback written with CustomJS
- added an initial x_range and y_range to the plot
- s2 ColumnDataSource is initially empty
