Olá pessoal,
Tenho um JPanel contendo um gráfico. Eu consigo até gerar outros gráficos, mas quando clico no meu JPanel ele volta ao estado inicial(de quando ele foi aberto). Se eu coloco uma data inválida, ele também volta meu gráfico para o “estado inicial”.
Alguma dica? To fazendo arte em algum canto mas sou muito noob ainda e não consigo encontrar onde
Tem muito lixo que o netbeans ta gerando no meio
