Hi!
I'm trying to make a clickable plot_date() plot (using the Pylons
framework). What I need is the pixel coordinates of the data points I
give to plot_date(), but the trans.seq_x_y() function doesn't like Datetime:
>> xcoords, ycoords = trans.seq_x_y(x, y)
float() argument must be a string or a number
How can I get the pixel coordinates?
Here are the relevant parts of my code (x is Datetime, y is float):
figure = pylab.figure(figsize=(6,4), dpi=100, frameon=False)
ax = figure.add_subplot(111)
# quick simple scatter plot
ax.plot_date(x, y, 'ro')
# Convert the data set points into screen space coordinates
trans = ax.get_transform()
xcoords, ycoords = trans.seq_x_y(x, y)
Thanks,
Erik
