Fig.savefig saving wrong graph

[wxcoding]

I am attempting to graph and save temperature and humidity daily data here, which appears to be working fine. Though a extra graph pops up before the one with the data on it, and when I attempt to save using fig.savefig() function it only saves the blank graph. Any idea why the blank graph is popping up? Code and images posted below.

fig,ax = plt.subplots()

ax = data_fr.plot(x='Time',y='Temp',color='r',figsize = (10,5))
ax2 = data_fr.plot(x='Time',y='RH',secondary_y=True,color='g',ax=ax,figsize = (10,5))
plt.title('Temperature and RH Daily Graph')
ax.set_ylabel('C')
ax2.set_ylabel('%')
plt.tight_layout()
name = str(file[:-9])+ ' T-RH Graph.png'
fig.savefig(name, dpi=fig.dpi)
