Support in the order you meet it.

• What is Hue Charts?

  A chart library. You give it your rows and a chart's spec, and it draws the chart by a fixed rule: the same picture on every machine. It runs in a web page, as the <hue-chart> element, from npm, as a Power BI visual, and through an assistant over MCP.

• Can I try it without an account?

  Yes. Every chart in the Chart Studio draws live in your browser, and the chart API and the MCP server are open to read. A free account is needed to download anything: the free packages, their SBOMs, the sample data and the test kit. The paid packages and the Power BI visual come with a Business or Enterprise plan.

• Where does it run today?

  On the web, from the package (the downloads have it now, npm at release) or the <hue-chart> element; in Power BI; and in any assistant that speaks MCP. Tableau is next, then Jupyter and Python notebooks. Platforms has the rest.

• Does it send my data anywhere?

  No. It draws on the machine it runs on and calls nothing home, and there is no key or licence file to check. The one chart that can fetch a live forecast draws its sample without a network.

• Is Hue Charts released?

  1.0.0 is cut and downloadable with a free account; npm follows. Until it does, it is in beta. It is free to use for any use, commercial included, under the Hue Charts Licence. A Business or Enterprise plan covers a whole organisation from the day it is bought.

• Which plan do I need?

  Free for anyone, for any use, commercial included: every everyday chart and every feature, the charts of science to try in Chart Studio, the Hue Charts credit on every chart, and 100 boards and charts a person. Business for a whole organisation: the paid packages, which draw no credit and draw the charts of science, the Power BI visual, 1,000 boards and charts a person, an email reply the next business day, the standards and law pack, and a vote on the roadmap. Enterprise adds the SLA, signed with your organisation, a named contact, 10,000 boards and charts a person, and one feature built for each three months paid.

• What does a plan add to the charts?

  The charts of science: the ECG, EEG and Holter, chromatograms and spectra, Bode, Smith and polar plots, the hypnogram and the rest, with the readers of their files. They take the most support, so they come with a plan: Business with an email reply the next business day, Enterprise with the SLA signed with your organisation. On Free, each draws its sample in Chart Studio to try.

• What does it cost?

  Free is free. Business is £1,000 a year or £100 a month, and Enterprise £5,000 a year or £500 a month, each for the whole organisation, with no seats. Boards and charts past a plan's number are £0.72 a year or £0.06 a month for each further 1,000 boards and charts a person, or part of them, billed at the renewal. Yearly or monthly is chosen when you buy. One published price, no quotes and no sales call. Pricing sets it out.

• Who does a plan cover?

  Everyone in your organisation: its employees, and its contractors while they build for it. There are no seats to count, and viewers, charts, servers and domains never counted.

• Who may buy a plan?

  Plans are sold to organisations and to people buying for their work, not to consumers. A person may buy one for their own work, on a personal account.

• How do I make an account?

  From Pricing. Start free makes a free account with a work email and a password, or with Google. Buy Business or Buy Enterprise makes the account and then takes you to payment. Have one already? Sign in.

• How do I pay?

  On Stripe's own page; you come back to Hue Charts when it is done.

• Can I join my company's organisation?

  Only by invite. Nobody searches for an organisation or asks to join one: its operator invites you by email, and you accept from the link they send.

• Is it free for open source, teaching or charities?

  Yes, and for everyone else: Free is for any use, commercial included, with every everyday chart. The credit stays on its charts, and the charts of science come with Business and Enterprise.

• How do I get the package?

  Sign in, then open Downloads in the header: the free packages, the <hue-chart> test kit, a sample CSV and the SBOMs, each with its SHA-256 and size, for any account. On a Business or Enterprise plan, the paid packages, their SBOMs and the Power BI visual are there too.

• Where are the docs?

  The chart API lists every function and element as it ships. The Chart Studio sets up any chart and hands you its spec. The MCP server connects an assistant.

• What is the Hue Charts credit?

  The words “Hue Charts” in the corner of every chart the free packages draw, in the note ink; on a web page, in the <hue-chart> element, they link to Hue Charts. Nothing switches it off. The paid packages and the Power BI visual draw none.

• Can I go live on Free?

  Yes: build with it, ship it inside what you make and sell what you make with it, at any scale, free, with the credit kept on its charts. The licence says so in full.

• How do I draw charts with no credit?

  Download the paid packages. While your organisation's plan is in force, Downloads gives them beside the free ones, with the same names, the same versions and the same code. Install the paid file in place of the free one; no code changes. Your own pictures lose the credit's row, so their digests, and any golden files you keep, move once.

  There is no key or file to read, and nothing calls home: the licence says who may use them. The paid packages are downloads from huedraw.com alone, never on npm; your organisation may keep them in its own private registry for its own people.

• Does a plan cover every platform?

  Yes. The paid packages carry the MCP servers and the <hue-chart> element, and the Power BI visual is built from them. Your organisation's Fabric administrator adds the visual; Platforms says how.

• Where is the standards and law pack?

  On your account, under Download the pack: the accessibility report, the law and standards, the SBOMs, the SECURITY file, the SLA, the plan terms and the data statement, in one file, dated by its release.

• What happens if the plan ends?

  What your organisation shipped or published with the paid packages or the Power BI visual while the plan was held keeps running. A build made after it ends, a rebuild included, is made with the free packages, and the paid downloads stop. No new report takes the Power BI visual; the reports that hold it keep drawing while your administrator keeps it. Your boards and charts stay, readable and editable; above 100 a person, no new one is kept until a plan returns. The organisation stays open, on Free.

• How do I invite my team?

  As the organisation's operator, open your account and use Invite someone: an email, an optional name and a role. You get a link to copy and send yourself; nothing is emailed for you, and the link is shown once. It expires after 14 days.

• Someone sent me an invite link. What now?

  Open it, sign in or make an account with the address it was sent to, and press Accept. If the link no longer works, ask the operator for a new one.

• What can an operator do that a member cannot?

  An operator buys and holds the organisation's plan, invites and removes people and changes roles. A member works under the plan. An organisation always keeps at least one operator.

• How do I turn my personal account into an organisation?

  On your account, under Make it an organisation, name it: there is no charge, and a plan you hold carries on, covering everyone you invite. An organisation does not go back to a personal account.

• How do I switch, cancel or close?

  Manage billing switches your plan or its period: a switch that costs less waits for the end of the period you have paid for, any other is made at once. Cancel the plan ends it at the end of that period, and Keep the plan undoes it until then; the organisation stays open, on Free. Its operator closes it with Close the organisation once no plan is live, and its members keep their own sign-in, as free accounts.

• Where are my invoices?

  Manage billing, on your account, opens your billing on Stripe.

• How do I sign in?

  With your email and password, or with Google. GitHub sign-in is not offered yet. Forgot your password? Ask for a reset link.

• How do I close my account?

  At the foot of your account page, Close my account. It is refused while you run an open organisation or your own plan is live or ending, so end those first. If you ever paid, your billing record is kept for seven years, as the law asks, and then erased; your own data leaves when you close. If you never paid, everything is erased at once.
