Your _visualMap_ has ```categories: ['malfunction', 'drift']```. All values equal to one of these two categories are treated as _inRange_, everything else (like _null_) is _outOfRange_. So seeing _null_ as circle is expected behavior. If you add a **data pre-processing** step to replace all nulls with 'malfunction', then the chart will display as you expect. However there is another **bug** that I think has not been reported so far. The second (green) line data starts with multiple _null_ values and shows the entire line as "empty" even though there are 'draft' values. The workaround is to replace the first record _null_ value with an empty string - [Demo](https://echarts.apache.org/examples/en/editor.html?c=line-simple&code=PYBwLglsB2AEC8sDeAoWszGAG0iAXMmuhgE4QDmFApqYQOQCGAHhAM70A0x6wpAJrQYA3RtgCu1ACLU2AY3rEAvt3RtaEWYQDaPIiRLRGAW2oMQACQC0AdVphYAOQhhysAIwA6d1z3owAJ4gZrD02BDQ1L4G6PyMYIzqYACS0ILMhAAMeip6qDGwRqbm1nakDs6uELAATN7RMYHBDOGRDQZxCUmp6YTuOcQAuqqwwuziYgCyjAT6JE0h9CCactQA7uxRI2oAFsBrhABmYurbsHLx1BR8mmw69MZih-LQcpAwXKH85Idg9MN6dTkWQ9agZWDaTKcdwAjoQUzQNhQaCEGpnCIAJUY0BohHyMTYAWMACMcAwqtiKNgtn5YISSTgAMoQABeIQAnGd0HIcHwGABiABigoALJkAMzsxQGXIGYDiMAAeUOWJxIXxBnppOwDGoxnAAQAwhBSHJqdKSEplCNqTQ0njAXsDmRJNbiJ1EtQwDo8rSIPwGDUAOwi9okfjw6iI5F3CH0SCmNgJfWfB7URLiUh6qN_TihWikPj_Ll0-WmkK6ArobT0GqZGoiqzuTJWGoAVgAKplMvhu73MgBqev9z5Bzxo0KPbDPV7vaDF2 nV2v1xvN1sANi7Pb73aHNRHebHNXcefo3wgvwXVbjdYbTZbwa3_f7e4PsCPJ6-Pz-sKrNdvq4PgAHE-O6Dpk7hvh-p7npev4FP-K73q27Kgdu4GQd2o7jp-DxPC8bzIlef7Lnea7iu4aEvhBUHjiKMHfsRCGkau7hWBBVG7jRWGHuODEXj-JZLgBTZsfWnEYbRx78XBQk3kh7hieKElDphmTYdJX4CUxMSIWRYkiip3HqbxNTijJgmLvJ-nsZ2YHUWpGlthZOkGHprHsZu9lcY5pnmZO-GzkRgy0iFMpnBqJD-oGQE1GGsSRtGMCxjWCayMmICpqYGZZgiub5qQhakK5paZqsPrXgA9JVhRgg4rTUIU4jYNgsBZiA2CMKs_CwBsYA7KEnxJLAxJdQA1hgwBNS1k10tQjX9Y1xLiBQVnuch7ZGfuPHvuOzmDfBuksRtXnodR20mbtNQTtAzXYIdbnHWuj7eeBF0aeuea3S1D0kOtz0ga9qm0f5333XJ_0PqhQPGRpnLTeDa1PS2FFGb5V1AS5v3CQpYmUTD6NjhRWMQ09Yk1GjIP-WejHY9ZHkSpTO1E_RWmyUjImKexhkEyD-009pdP_WJdlnT5IOfWzlnXsLnlM5dROYwjYUxCr6BWugv4BAAgqwsaRQsIhiJIYbGBEDAepMEQWrKsDMLr7AOgYhuhGlNsoEoADcQA)  -- This is an automated message from the Apache Git Service.
