Plotting Interactive Bar Plot in Bokeh

Hi Team,

I was trying to plot bar graph using bokeh and facing following issues.

1. Interactivity is not there, I am using bokeh.charts and Bar library to create bar charts.

Below is the detail of the plot/function I am using:

def make_plot_promotype(source, title):
df=source.to_df()
bar = Bar(df,‘promotion_type’,values=‘value’,title=title)
return bar

Below is how I am calling this make_plot_promotype function

plot_sales_by_promo = make_plot_promotype(source_sales_by_promo, “Sales by Promotion Type”)

Now plotting this bar chart using

curdoc().add_root(HBox(plot_sales_by_promo))

The problem with the above code is that I am seeing two curves while running this application through bokeh server. One where I have called

plot_sales_by_promo = make_plot_promotype(source_sales_by_promo, “Sales by Promotion Type”)

and another is inside curdoc() function.

for implementing interactivity I am using call backs like this:

year_select.on_change(‘value’,update_plot)

where inside update_plot I am changing and update the source dataframe.

2. Another problem with bokeh bar charts is that I want labels as strings on the X-axis but could not do this.

Appreciate your help on the same team.

Thanks,

Saurabh Heda

Somehow managed to plot Bar using rect but now the problem is related to the x axis labels. following is the code to plot the rectangle.

def make_plot_promotype(source, title):

• label=[‘promo1’,‘promo2’,‘promo3’,‘promo4’]*

• yr = DataRange1d(start=0, bounds=None)*

• df=source.to_df()*

• plot = Figure(plot_width=500, plot_height=400, toolbar_location=“above”,y_range=yr)*

• plot.title = title*

• plot.rect(x=‘promotion_type’,y=‘valuebytwo’,source=source, width =0.5, height = ‘value’, legend=title)*

• plot.xaxis.major_label_orientation = np.pi/4 # radians, “horizontal”, “vertical”, “normal”*

• return plot*

source is the columndatasource which is pandas dataframe. promotion_type, valuebytwo and value are the columns of the dataframe.

Above is the plot we get while x_range = label is not supplied but while figure is supplied with x_range = label getting the below curve.

plot = Figure(x_range=label,plot_width=500, plot_height=400, toolbar_location=“above”,y_range=yr)
