# Graph of eigenvalues of Maass forms of levels 100 to 1000 with $0 \leq R\leq 1$

The horizontal axis is the spectral parameter $R$ with the Laplace eigenvalue
satisying $\lambda=1/4+R²$. The vertical axis is the level $N$. Each point
corresponds to a Maass form of weight 0 and trivial character on $\Gamma_0(N)$
with the color showing whether the symmetry is **even**
or **odd**. Clicking on a dot takes you
to the homepage of the Maass form. For $N>100$ there are only results for prime level.
