marginsplot interpretation

[Maria Sevillano]

Good afternoon,
I am conducting a Fixed Effects panel data analysis for 17 MENA countries to test the hypothesis: oil and natural gas rents increase millitary spending. I have introduced an interaction variable between oil and gas and it is positive and significant. I have created a marginsplot. Can someone help me to interpret the results or tell me if I am in the right direction? I attach the results
Thanks.

Can I say that when countries have vast oil rents but no rents from oil, the impact of oil rents on military spending is negative. But the effect of oil depends on the amount of gas rents. When gas rents are different than 0, the impact of oil rents on military spending becomes positive?
